1 Corinthians 1:2a
To the church of God which is at Corinth, to those who have been sanctified in Christ Jesus, …
In John 17:16-17 Jesus prayed and declared we are in the world but not of the world, and that we would be sanctified (set apart) from the world by the truth of God’s Word. Once born again we should no longer live the way of the world. We begin to live a life set apart from fear, worry, doubt, sin, sickness, etc. All these things are in the world and are true, but there is Truth that reveals we have been set apart from all of that, God’s Word. If we will learn from the Word of God who we now are in Christ and become doers of the Word and not just hearers only, we will be set apart by the Truth. Become one with the Word of God by hearing and doing the Truth, and you will live a life set apart from the world.
