“Give thanks to the LORD, for He is good! His faithful love endures forever.” (Psalm 107:1 NLT)
Returning thanks for blessings already received increases our faith and enables us to approach God with new boldness and new assurance. Doubtless the reason so many have so little faith when they pray is because they take so little time to meditate upon and thank God for blessings already received. As one meditates on the answer to prayers already granted, faith waxes bolder and bolder, and we come to feel in the very depths of our souls that there is nothing too hard for the Lord. As we reflect upon the wondrous goodness of God toward us on the one hand, and upon the other hand upon little thought and strength and time that we ever put into thanksgiving, we may well humble ourselves before God and confess our sin.
