66 Bible verses about the power of Fasting

The power of fasting really lies in honestly opening your heart to the Lord. It's in that space where His love shines through and transforms every part of who you are. Fasting is something you do when you’re truly seeking Jesus, when you're willing to sacrifice physical needs to ask for a deeper connection with Him.

It strengthens your spirit, grows your faith, and draws you closer to God. By saying "no" to the physical demands of your body, you're saying "yes" to a deeper, more intimate relationship with Him. It's about prioritizing that connection above all else.
