I speak on this subject in reference to the Christian being separated from the world. See Eph. 5:25-27; Col. 1:20-22; 1Cor. 1:26-31; 6:11; 1Thess. 4:4; 1Peter 2:9-12 and Titus 2:11-15. The main subject of these texts is sanctification, which means "set apart". The subject of separation is losing popularity in an ever-increasing way in our time. The liberals call us "legalists" because of it. The Word of God calls us "worldly" because of it. The world calls us "weird" because of it. We have even been called "cult" because of it. Look at Lev. 20:1-8, 22-27 and notice: Verse 7 "Sanctify yourselves therefore, and be ye holy." Then in v.24, "I am the LORD your God, which have separated you from other people." See again vs.25-26 as well. In 2 Cor. 6:14-18 we see the New Testament command for separation as well. "Come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you." Read 1 Cor. 5:1-13 and see again where God commands separation. Now let me give you several reasons why God tells true believers to be separate.
- Separation is for our protection.
Notice in 1 Cor. 5:6 "A little leaven leaveneth the whole lump." James 1:27 states, "Pure religion and undefiled before God and the Father is this, to visit the fatherless and widows in their affliction, and to keep himself unspotted from the world." See again 2 Cor. 6:17 "and touch not the unclean thing." See 1 Cor. 3:17 which warns of defiling the temple (our body).
- Separation is a mark of identification.
2 Cor. 5:17; Eph. 2:2-3, 5:8 and 1 Pet. 4:1-4 Show that separation draws a line between our past and our present. Separation from the world is a convincing proof that we are indeed "new creatures." Christians always stand out in the world. Rom. 12:1-2 states we are transformed by the renewing of our mind.
- Separation if a mark of dedication.
1 Cor. 10:23-33 Separation involves going against the world, the flesh and the devil. It does not come naturally, rather supernaturally. It is a Spiritual choice. "If separation is not born out of dedication, it will not have long duration."
Gal. 2:20 gives the key to separation. "I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave Himself for me."
1 Cor. 10:31 says, "Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God." I have often told my Church that we should never do anything that we cannot invite Jesus to do with us.
