He may establish your hearts blameless in holiness. 1 Thessalonians 3:13
Today’s verse is Paul's earnest prayer for Thessalonian believers, his strong desire is that the Lord may establish their hearts without blame in holiness before our God and Father – at the coming of our Lord Jesus Christ with all His saints. Salvation experience is only the first step in spiritual growth and the final step is to be transformed into the image of Lord Jesus Christ. God chose us in Christ before the foundation of the world, that we should be holy and without blame before God the Father in love. Once a believer in Jesus Christ is saved, every day we need to ask God to purify our hearts as it is deceitful in all, and this process is called Sanctification. Sanctification is not Holiness. Sanctification is the process of being made holy and Holiness is the element of God’s holy nature.
Our hearts are established when we are perfected in faith and abound in our love. For our heart to be established blameless in holiness, not only should our heart turn to God and be pure, but it also needs the element of holiness added to it. To be holy is to be separated unto God and fully occupied by Him and saturated with Him. Once our heart has been established, it will be set, and it will be no longer movable or changeable. Furthermore, when our heart is in such a condition, it will become blameless. The way for our heart to be blameless is for it to be established by the Lord. If our heart is established by Him, we shall be those whose heart has been separated unto the Lord, occupied by Him, and saturated with Him. Then our hearts will be set, established, built up, blameless in holiness. May the Lord help us.
