I can't be a good person period, only God is good. I am wicked and unclean apart from Christ. When God sees me now that I know Christ as my Saviour, He does not see me, but His Son Jesus Christ instead. Jesus' account is perfect and clean, while mine was full of sins commited. It is not me that God looks at to let me into Heaven. I have nothing desirable for God and neither does any of us, sir, but it is His Son that He sees.
