Fasting as God’s Pathway to Consecration
Consecrate yourselves, for tomorrow the Lord will do amazing things among you. - Joshua 3:5
Fasting is a time-honoured divine means of purification and preparation. Fasting is not merely abstaining from food; it is a sacred discipline through which God purifies motives, refines character, and aligns human vessels with divine purpose.
Throughout Scripture, God consistently prepares His servants before He uses them or entrusts them with His work. Before Israel crossed the Jordan into the Promised Land, they were commanded to consecrate themselves. Before Jesus began His public ministry, He fasted in the wilderness. Before the early church launched into global mission, believers gathered in prayer and fasting.
What is Biblical Fasting?
Biblical fasting is not merely abstinence from food. While abstinence from food is the outward expression, the inward posture is humility, repentance, and surrender. True fasting engages the whole person by quieting the fleshly appetites and causing the spirit to become more sensitive to God’s voice.
It is important to remember that fasting is neither a spiritual shortcut nor a method to manipulate God. Instead, it is intentionally placing oneself under God’s refining hand.The goal of fasting ought to be spiritual transformation alone.
Fasting must be practiced with wisdom and sincerity. It must deepen prayer life, sharpen spiritual sensitivity, cultivate humility and strengthen self-discipline. True fasting will always lead toward greater love for God, deeper compassion for others, and renewed obedience to Scripture. If fasting produces pride, harshness, or self-righteousness, its purpose has been missed.
Fasting and Purification: God’s Refining Fire
The psalmist prayed: Search me, O God, and know my heart; test me and know my anxious thoughts. (Psalm 139:23)
Fasting and praying while deeply dependent on the Word should allow us to experience inner cleansing. This is when we allow the Holy Spirit to confront in us the sin, arrogance, misplaced desires, and spiritual depravity. This should never be seen as a failure of fasting. This, in fact, is what fasting and praying does – revealing to us that which needs to be discarded from within us. This indeed is the searching and cleansing work of God.
In Scripture, purification frequently precedes divine movement. God prepares us, His chosen vessels by purifying our inner lives.
Jesus warned His disciples:“When you fast, do not look somber as the hypocrites do… but when you fast, anoint your head and wash your face.” (Matthew 6:16–17)This is a warning that our fasting should redirect our heart toward God rather than be presented before men for applause.
As we engage in ministry, our prayer should be that our fasting will cause us to ask these searching questions:Whose approval am I seeking?Am I willing to obey even when unseen?
Fasting should help align calling with character.
It is encouraging to look at four instances in the Old and New Testaments of those who were purified before God’s purposes were fulfilled through them.
1. Moses: A ReluctantLeader to Covenant Reconciler
Moses fasted forty days on Mount Sinai – he was in God’s presence without food or water, before receiving the renewed tablets of the covenant (Exodus 34:28). This was a sacred encounter when he was completely dependent on the Lord. This was not simply a period of consecrationbut a scared moment when Moses received divine instruction that would shape Israel’s spiritual life. Scripture records that his face shone with God’s glory when he descended from the mountain. The people immediately recognized that he had been in the presence of the Lord.
This spiritual encounter entrusted Moses with deeper spiritual authority. He became the man through whom God’s voice; His Law and guidance were delivered to the people of Israel. Moses was not just a political leader; he was seen as a spiritual leader too – a mediator of the covenant. All this tells us how Moses’ fasting prepared him to receive the divine revelation and also serve as covenant reconciler.
2. Esther: Passive Queen to Undaunted Deliverer
When the Jewish people faced destruction under Haman’s decree, Queen Esther called for a three-day fast among all the Jews (Esther 4:16). Though she held royal status, approaching the king without invitation could cost her life.Esther called for a three day fast. Those were days of consecration which transformed Esther’s fear into courage. With boldness, Esther approached the king and found unexpected favor. Through wisdom and divine timing, she exposed Haman’s plot.
The result was a remarkable. Haman was removed from power, Mordecai was elevated to a position of authority, and the Jewish people were granted protection throughout the Persian empire.
The fast that began in crisis ended in deliverance. God used a purified and courageous woman to preserve an entire nation.
3. Jesus: From Wilderness to Spirit Empowered Ministry
Before beginning His public ministry, Jesus was led into the wilderness where He fasted for forty days and forty nights (Matthew 4:1–2). During this time of fasting, He faced direct temptation from Satan, each time with an offer to quick power and easy miracles. Yet Jesus resisted each temptation through Scripture and unwavering devotion to the Father’s will.
After this fast, Jesus returned “in the power of the Spirit”, to begin His ministry with authority. Demons were cast out, the sick were healed, and crowds gathered to hear His teaching. The wilderness fast was a hidden preparation time before Jesus was launched into public ministry.
4. The Early Church: From House Church to Global Mission
The church in Antioch gathered for worship, prayer, and fasting, as we read in Acts 13. This was a time of consecration when the Holy Spirit spoke clearly: “Set apart for me Barnabas and Saul for the work to which I have called them.” Fasting and praying created the spiritual environment in which God’s direction became clear.
The church responded by laying hands on them and sending them out. What followed was the beginning of the great missionary movement of the early church. Through the journeys of Paul and Barnabas, the gospel spread across Asia Minor and into Europe, establishing churches among the Gentiles. Out of that moment of consecration emerged one of the most significant missionary expansions in Christian history.
There is a profound connection between inner purification and spiritual authority. Jesus told His disciples that certain spiritual victories come only through prayer and fasting (Mark 9:29). Authority in ministry flows from a life surrendered to God.
A Personal Testimony
In our own journey of ministry, we have seen this principle lived out time and again. There have been seasons when the Holy Spirit gently prompted us to set aside time for fasting and prayer. During those moments, my husband, Lt.Col. Luke and I did not know what God was preparing us for, but we sensed clearly that He was inviting us into deeper consecration.
Looking back, we realize that those hidden seasons of fasting and prayer were not merely devotional exercises but God’s way of quietly refining our hearts, aligning our motives, and preparing us for the fruitfulness, and responsibilities that would unfold later in our ministry. Our personal experience has reinforced a truth we see throughout Scripture: God often prepares His servants privately before He uses them publicly.
Consecration Before Commission
Academic training, ministerial skills, and theological knowledge are valuable, but they cannot replace the inner work of consecration.
For those preparing for ministry, the biblical pattern remains clear. In God’s economy, hidden surrender precedes public service. Before the platform comes the wilderness. Before authority comes obedience. Before promotion comes purification.
Joshua’s ancient command still speaks powerfully to us today. Are we ready to consecrate ourselves, believing that tomorrow the Lord will do amazing things among us?
May we who fast do so not for recognition. May our hearts be refined, our motives pure and our lives fully surrendered to God’s purposes.
If anyone cleanses himself… he will be an instrument for noble purposes, made holy, useful to the Master and prepared to do any good work. 2 Timothy 2:21.
May God find in each of us a consecrated vessel, ready and fit for His gracious use.
