Seventh-Day Adventist Church
Spiritual progress is dependent upon God. It's in the Bible, Philippians 1:6, TLB. "And I am sure that God who began the good work within you will keep right on helping you grow in His grace until His task within you is finally finished on that day when Jesus Christ returns."
Spiritual progress is a process of not giving up. It's in the Bible, Philippians 3:13,14, NIV. "Brothers, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead, I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus."
