Perfectionism is a trap. It causes us to depend on our works for salvation and acceptance with God when Jesus already made the way for salvation, and Jesus already accepted us into the beloved.
To the praise of the glory of His grace, wherein He hath made us accepted in His Beloved. – Ephesians 1:6
He has already committed to perfecting the things that concern us. We have to genuinely look to Him and trust in him to do what he said.
Being confident of this very thing, that He who hath begun a good work in you will perform it until the day of Jesus Christ. – Philippians 1:6
Resting in our acceptance from Christ also lightens the burden to appear perfect or acceptable to men. When we make a mistake, we can more easily own our mistake because it doesn’t affect our acceptance with God. At that point, we are free from the fear of humiliation. Mistakes cannot be held over our heads in the same way; when we know who we are in Christ.
