Our Scripture reading today is 1 Thessalonians 4:3, "For this is the will of God, even your sanctification, that ye should abstain from fornication."
At times, we might wonder exactly what is the will of God for our lives. The Apostle Paul writes not only to the church at Thessalonica but also to us today with regards to something that is the will of God: our sanctification. God wants us to be less and less like the world and more and more like His Son, Jesus Christ. This is a process called sanctification. As we yield to the Spirit of God, we will in turn be headed toward sanctification.
The difference between salvation and sanctification is time. Salvation is not a process. We are not becoming saved. We are either saved or lost. Like our physical birth was a moment in time, so is our spiritual birth. Sanctification cannot be traced back to a moment in time. It is many moments from the time of our salvation until we are in Heaven. The lyrics that help me understand this TRUTH are, "He's still working on me to make me what I ought to be. It took Him just a week to make the moon and the stars. The sun and the Earth and Jupiter and Mars. How loving and patient He must be. He's still working on me."
