We all want to be accepted, but there are very few relationships we may ever experience that show us unconditional acceptance. That isn't how people typically operate. I learned very early in life that many people in this world accept you right up to the point when you stop giving them something or stop doing something for them.
But thankfully, that's not how the acceptance of God works. His acceptance of you and me is not linked to what we can give Him or do for Him. Rather, His acceptance of us is forever tied to what He did on our behalf, and what He gave us through His Son, Jesus Christ.
