We must balance “Forgive us our sins, for we also forgive everyone who sins against us” Luke 11:4a (NIV) with “Whoever is born of God does not sin”  1 John 3:9.  The key is intentional sin.  The Father’s children want to obey Him.  They have in themselves the seed of the Father because they have been born of God, therefore they do not sin presumptuously.  When they discover in themselves some unloving act, they do not hide it or cover it, but they do confess it.

“My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous.” 1 John 2:1 (NKJV).
