“Let us go forth to Him, outside the camp” (Hebrews 13:13)  

The reason the Christian leaves “the camp”, which represents the world's sin and religion, is not because he wants to be different, but because the disciples of Christ must follow Him. “Come out from among them And be separate, says the Lord. Do not touch what is unclean, And I will receive you" (2 Corinthians 6:15). Christ was "not of the world"; His life and His testimony were a constant protest against conformity with the world. Christ overflowed with affection for humanity, but at the same time, He was separate from sinners. In like manner, Christ's people must "go forth unto Him”. “What communion has light with darkness? ... what agreement has the temple of God with idols? For you are the temple of the living God” (2 Corinthians 6:14-16). 

 You must take your position "outside the camp", as a witness to the truth. “Denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present age” (Titus 2:12). You must have a bold, unflinching, courageous heart, loving Christ first, and His truth next, not loving the things of the world (1 John 2:15). Christ would have His people "go outside the camp", for their sanctification. “Do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God” (Romans 12:2). You can’t grow in grace when you’re conformed to the world. The life of separation may be a path of sorrow, but it’s the only safe path; and though the separated life may cost you friends, and make every day a battle, it’s the only way to have “righteousness and peace and joy in the Holy Spirit” (Romans 14:17).

 “No one engaged in warfare entangles himself with the affairs of this life, that he may please him who enlisted him as a soldier” (2 Timothy 2:4). Christ gives special grace to those who need it to accomplish His work. You find out how precious the Holy Spirit is when you need Him most. The soldier feels more calm and peace in his daily fight than others feel in their hours of rest. “For our light affliction, which is but for a moment, is working for us a far more exceeding and eternal weight of glory, while we do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal” (2 Corinthians 4:17-18).
