If it were not possible to live a holy life, God would not have commanded it. He said, “You shall be holy, for I the Lord your God am holy” (Leviticus 19:2). To be holy means to be separated to God. Something about God’s nature itself speaks of holiness. Being set apart to God makes us holy.
We are not made holy by doing good things. We are made holy by faith in Christ, just as we are saved by faith. Little by little, as we grow and live with the Lord, we will become more like Him. Paul said, “We all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord” (2 Corinthians 3:18).
As we look at Jesus, think about Jesus, study about Jesus, pray to Jesus, and seek to follow His example, we become like Him. We begin to think like Him and act like Him. We become like Him because we are set apart to Him. This is true holiness.
If you are a Christian, ten years from now your life should be considerably different from what it is now. Your motives and desires, as you get closer to Him, should be continuously more holy.
Jesus said, “Blessed are the pure in heart, for they shall see God” (Matthew 5:8). We can achieve a degree of purity in this life. It comes from God, as we grow closer to Him and are more like Him. Although perfection is not totally attainable in this life, it is something we should strive toward and aim for.
