When we want to enter into God's presence He does not examine us to determine our worthiness. He sees our value through His Son. It is Jesus and Jesus alone that presents us to our heavenly Father without a spot or wrinkle, holy and without blemish, innocent of sin.
So come, just as you are, wherever you are. Worship God for who He is, not what He is. When we are God conscious and not sin conscious in our worship we can hear Him say, Beloved, you are forgiven, you are healed, you have been made whole.
