S – For God has not called us to impurity but to live in holiness. 8 Consequently, anyone who rejects this does not reject man, but God, who gives you his Holy Spirit.
1 Thessalonians 4:7–8 CSB
O – Some great Commentary:
To impurity: Better, for uncleanness; ἐπὶ denoting aim or intention. The intention is viewed as the basis of the act
In holiness: Note the change of preposition. Sanctification is the characteristic life-element of the Christian, in which he is to live. Comp. in peace, 1 Cor. 7:15; in hope, Eph. 4:4.
Word Studies in the New Testament
God Paul’s instructions about holiness are based not on human philosophy or tradition, but on God’s holy character as the standard for behavior (1 Pet 1:14–16 – “Be holy, because I am holy.”)
A – In calling us to his character, God looks at our intentions as much as our actions. Only God can see the heart. Holiness is one of those characteristics (like hope and peace) in which God exists in us through the Holy Spirit. Even though we are not perfect, we must move towards holiness and not our own human nature.
R – Lord, help me to do this today.
