7 For God has not called us for the purpose of impurity, but in sanctification.8 So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you.
1 Thessalonians 4:7-8 NASB
Sanctification means holy, separated to God. This is the life that God has called His people to.
This is something awesome that the blood of Jesus has done for us, made us holy and separated to God. But there is also something real we should do as well.
Paul talks about here in this chapter that there are actions and responsibilities that the believer has, like, abstain from sexual immorality. We should check our lives, actions and beliefs to make sure they are holy to God.
Verse 9 says that if we reject sanctification, we are rejecting the Holy Spirit, because this desire to be holy comes from Him.
If God has called me for the purpose of sanctification, am I doing my part in regards to being holy? Obviously I can’t become holy in my own right, I need to accept Jesus as my Lord and Savior. But am I doing my part by controlling my passions, lusts, etc. There are simple things I can do to help here: watch what I put in my mind (TV, movies, books), evaluate the people I let influence my life, fill my mind, spirit and heart with the things of God. Why wouldn’t I want to do this? Why wouldn’t I want to be pleasing to the Lord?
Lord, help me to walk in sanctification. I know that while I live on this Earth, I will never experience or walk completely in what You have for me. But one day, when this world passes away, Your people will be in a place that is completely separated to You and the lusts of the flesh and desires that creep up now will be gone.
Until then, help me to walk in Your ways. I want to stay close to You and what You desire for my life.
