1 Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship. 2 And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect. Rom. 12:1–2, NASB
One of the markers of genuineness in a Christian is separation from the world. This isn’t a physical removal from planet Earth or a disintegration of the body of a Christian. A genuine Christian’s character should be in a continual upgrade unto Christlikeness. That means that as he or she cooperates with God in their sanctification, working out their salvation with fear and trembling, their character will take on more and more of Christ’s character. They will love what He loves and hate what he hates. God is love, but He hates a certain type of love.
