“For God sent not his Son into the world to condemn the world; but that the world through him might be saved.” (John 3:17)
A critical spirit cannot be pleased. No matter what you do or say there will be something wrong in it. When someone has soured on you they have left off believing you can be any different than you were yesterday. They have you forever locked in the past they won’t let go of.
A critical spirit is a spirit of condemnation. When a person is condemned, final sentence is passed. Jesus did not come into the world to condemn us because we all were already condemned. We were condemned not because of what we had done, but because of who we were. Every child of Adam is born a sinner who cannot please God. Jesus did not come to simply forgive us for our sins, but to change our state of being – to turn sinners into saints.
When you were without strength and hopelessly lost, God did not give up on you. Thank Him that He did not have a critical spirit toward you. He could have passed final sentence on you, but He was not willing for you to perish.
No matter how egregious another is, make sure you don’t condemn them. Can you change them? No. Can they change themselves? No. Can God change them? Yes. For this very reason He sent His Son into the world.
