1 Corinthians 1:2a
To the church of God which is at Corinth, to those who have been sanctified in Christ Jesus,…
The real you, the spirit man on the inside has been sanctified in Christ. The word sanctified means to be set apart and dedicated unto God. Sanctification of our spirit man was God’s part, now we respond by the consecration of our soul and bodies. Jesus in praying for His disciples said in John 17 that we would be in the world but not of the world. In His prayer He prayed we would be sanctified by God’s truth, for His Word is truth.
Once born again we don’t have to live the way of the world. We can 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.
Many today are being taught that they don’t need to do anything to consecrate themselves, but that is not what scripture teaches. Take a look at the following scripture:
2 Corinthians 7:1
Therefore, having these promises, beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.
Notice we are told to cleanse ourselves. This is something we must do once we are saved. We are to cleanse our life from all filthiness of flesh and spirit. The fleshly part deals with sins of the flesh. The spiritual part deals with things that are harmful to you spiritually, which refers to false teachings and just wanting your ears tickled. Don’t fall for the “feel good” preachers who won’t teach you how to get free from the fleshly man. When you know the full Truth of God’s Word, the Truth sets you free.
If we will learn from the Word 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 sanctified and consecrated life, set apart from the world.
