This sermon is the third in a series, entitled “Fatherly Encouragement,” based on texts from 1 Thessalonians. In this epistle the Apostle Paul encourages the Christians of Thessalonica who are young in the faith. He acts as their spiritual father. Today’s theme is based on 1 Thessalonians 3:11–4:12.

Fatherly Encouragement toward Sanctification

Focus Statement

Sanctification is God’s will for how we live and is empowered by him.

Function Statement

That the hearer may grow in sanctified living.


Every parent has hopes for their children. We want our kids to grow up to be responsible and productive adults. Parents provide guidance and encouragement to their children regarding how they are to live.

The Apostle Paul considered the Christians at Thessalonica to be his spiritual children. He was like a father to them. Appropriately, he had hopes for them—that they grow in the will of the Lord. Paul states frankly, “This is the will of God, your sanctification” (1 Thes 4:3).

God’s desire is for our sanctification as well. The text today gives us guidance and encouragement regarding how we are to live sanctified lives.
