We can all relate when it comes to falling short of expectations. Obedience to God is a learning process, and failure is a part of our development as humble servants. When we yield to temptation or rebel against God's authority, we realize that sin has few rewards, and even those are fleeting.
Failure is an excellent learning tool, God doesn't reward rebellion or wrongdoing. However, by His grace, He blesses those who choose repentance and embrace chastisement as a tool for growth. Failure teaches believers that it is much wiser and more profitable to be obedient to the Lord. That's a lesson we all should take to heart.
PSALM 73:26 - My flesh and my heart fail; but God is the strength of my heart and my portion forever.
