Now may the God of peace Himself sanctify you completely

1 Thessalonians 5:23
Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.

Paul prays that the believers will be sanctified. The sanctification process should be for all believers. It means to make pure and perfect. Although we still live in a sinful world, the Holy Spirit will guide the followers of Christ to sanctification if only we let Him.

Living in a sinful world will lead believers to battle with sin and tempations constantly. Many times, human will itself will not be able to win over tempations. It is only with the help of the Spirit that we can stand and be sanctified. This is also a process of surrender to Him and to entrust our battles to Him.
