We tend to have a scale...as if goodness can be measured, but God has no scale. God says that He is goodness. The only way we can ever be the standard of goodness He can accept is if we are in Him. Anything less than God isn't good enough.
Thankfully, this is not something we need to be disheartened about, rather we should be encouraged. God gave us His goodness in Jesus Christ, so that by taking Him on board, by giving ourselves to Him, we would be good enough to be in relationship with Him, which has been His desire since before the world began.
Sin separates us from God because it is unacceptable to Him, but Jesus reconciles us to God, because He was and still is and will forever be perfect and acceptable.
Put simply, Jesus makes it possible for us to be with God.
Welcome Jesus into your life and watch His goodness permeate through all your sin, so that you blossom, and reach and become all that God wants you to be.
