As they ministered to the Lord and fasted, the Holy Spirit said, "Now separate to Me Barnabas and Saul for the work to which I have called them." Then, having fasted and prayed, and laid hands on them, they sent them away. Acts 13-2-3
As they were fasting, the Holy Spirit spoke to them. Then they prepared for their journey by fasting and praying.
Fasting and praying are necessary when you have a big decision to make, or you are looking for answers and direction from God, or to prepare for a long undertaking.
Fasting is not easy. Fasting is not something that I want to do. Fasting is not a diet or a way to lose weight. Sometimes we are called by the Lord to fast and pray because he wants us to depend on him, to seek his will in our lives, and to trust him. Fasting takes effort, discipline, and forces me to focus on the Lord and depend on Him for my energy. When I am focused on the Lord is when I can hear Him the most.
Dear Lord, please help me when I need to take time to fast and pray for your guidance, your wisdom, and your direction. Help me to stay in tune to hear your voice when you are speaking to me. Help me to listen to you and to seek your will in my life.
