This is the will of God, your sanctification… 1 Thessalonians 4:3
"There is always a tremendous battle before sanctification is
realized— something within us pushing with resentment against the demands of Christ. When the Holy Spirit begins to show us what sanctification means, the struggle starts immediately.
We refuse to be identified with the death of Jesus Christ on this point. We say, “But this is so strict. Surely He does not require that of me.” Our Lord is strict, and He does require that of us."
Oswald Chambers
