Renewal takes time

Becoming a new person means that you must give up the way you lived before, not only to live a new life, but also to learn to think in a new way. The longer a person does certain sinful things, the easier it becomes to it and the more difficult it is to ge rod of the habit. If it becomes second nature to use bad language, be impatient and selfish, then it is impossible to suddenly become a new person in just a few days.

The sanctification process can last your whole life and you must have a continuous , intimate relationship with God. Sanctification will also test your endurance because you will most probably discover that, in spite of your best intentions, wou will sin again. But God can and wants to make it possible for you to live a holy life.
Heavenly Father, I pray that You will make me a new person, one who live in line with Your will.
Amen
