Dedicated to the Lord Jesus Christ Who loved us, gave Himself for us, and washed us from our sins in His own Blood; and to the Church, which is His body.

JOHN 4:24
Man dwells mainly in the physical and emotional realm, but God is a Spirit (1 Samuel 16:7). To have true fellowship with God, we have to relate to God on the spiritual level.
In order to do this, God changed our spirit. At salvation, our spirit became totally new (11 Corinthians 5:17). It is now righteous and truly holy (Ephesians 4:24). It is now exactly the way Jesus is, because our born again spirit is the spirit of the Lord Jesus Christ (1 John 4:17; 1 Corinthians 6:17; Romans 8:9; Galatians 4:6).
In our spirits we are worthy to come before God and worship Him without any fear. Our spirit is the only part of us that is worthy. That's why we must worship Him in spirit and in truth.
When we come to God dwelling on all our failures and problems, we are not coming to Him through our spirit. Our spirit is not our problem. Our born again spirit is perfect.
There is a place for mentioning our problems and failures but He already knows about them. We must always base our relationship with the Father on who we are in our spirit through Christ Jesus.
