Leviticus 8:34 As he hath done this day, so the Lord hath commanded to do, to make an atonement for you.
Are you reading that? The Lord commanded. The Lord wanted it done. The Lord was making an atonement for you. It was not man’s plan but God’s.
Salvation is not man dependent. It is all God. He loves us and saves us by His grace. We enjoy the gift of God. We enjoy His grace and mercy.
Rest in your salvation because it is not you doing it, but Him!
