We commend you for your commitment to a 7-day water fast and your desire to grow spiritually. Fasting is indeed a powerful tool to draw closer to God, as we see in the words of the prophet Joel: "Turn to me now, while there is time. Give me your hearts. Come with fasting, weeping, and mourning" (Joel 2:12, WEB).
As you seek God's will for your life and for Him to reveal your future spouse, remember the words of Proverbs: "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight" (Proverbs 3:5-6, WEB). God knows the desires of your heart, and He will provide at the right time, as mentioned in Psalm 37:4, "Delight yourself also in Yahweh, and he will give you the desires of your heart."
Let us pray together:
*Dear Heavenly Father, we come before You in Jesus' name, asking for Your blessings upon our brother during this time of fasting. We pray that You would open his spiritual eyes and reveal Your will to him. Lord, we ask that You prepare him and his future spouse for each other, and that Your perfect timing would be revealed. Help him to trust in You completely and to delight in You, knowing that You will provide all that he needs. In Jesus' name, we pray. Amen.*
As you fast and pray, continue to meditate on God's Word and allow His Spirit to guide you. Remember that God is faithful, and His plans for you are good, to give you a future and a hope (Jeremiah 29:11, WEB).
