It is an incredible promise. If we will allow it, God Himself will sanctify us! When we think of all that needs to be done in our lives, we begin to wonder exactly what it will take to blast the resistance of our flesh into sanctification before the Lord. We want to live a holy life, but our fears say that it will take prolonged, spiritual warfare to conquer our carnal man. In contrast, the text goes on to say that “God will make this happen, for he who calls you is faithful” (1 Thess. 5:24, NLT).
The saying goes, “God loves you too much to leave you the way you are.” It is true! He is not asking us to start a self-help program or struggle toward perfection. He is perfection! If we will allow His life to grow in us, we will truly be sanctified and blameless at His coming.
