you are not a failure
EPHESIANS 2:10 NIV
10 For we are God’s workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do.
You may have failed, but you are not a failure.
It is not the essence of what and who you are. Failure is just something that happened to you.
God created you, and He made you able to do good. Maybe you have not yet discovered what you were created for, but God has a plan for you. When you fit into God’s plan you will find that God truly made you “a work of His art.”
