"There is King Jesus marching at the head of his troops; and can it be that some of you, who profess to be his followers, are on the other side; that professing to be Christ's you are lighting in the ranks of the enemy—carrying the baggage of Satan and wearing the uniform of hell, when you profess to be soldiers of Christ? I know there are such here: God forgive them! God spare them; and may the deserters yet come back, even though they come back in the chains of conviction! May they come back and be saved! O brethren and sisters, there are enough to destroy souls without us—enough to extend the kingdom of Satan without our helping him. "Come out from among them; touch not the unclean thing; be ye separate." Church of God! awake, awake, awake to the salvation of men! Sleep no longer, begin to pray, to wrestle, to travail in birth; be more holy, more consistent, more strict, more solemn in thy deportment! Begin, O soldiers of Christ, to be more true to your colors, and as surely as the time shall come when
the church shall thus be reformed and revived, to surely shall the King come into our midst, and we shall march on to certain victory, trampling down our enemies, and getting to our King many crowns, through many victories achieved."
C. H. Spurgeon
I do believe people who are coming to Jesus want to change and be better people and want to know how. Should they be coming to Christ Jesus to be the same as before? I pray that we learn righteousness in and through Christ and not to become self-righteous.
Hebrews 5:
Warning Against Falling Away
11 We have much to say about this, but it is hard to make it clear to you because you no longer try to understand. 12 In fact, though by this time you ought to be teachers, you need someone to teach you the elementary truths of God’s word all over again. You need milk, not solid food! 13 Anyone who lives on milk, being still an infant, is not acquainted with the teaching about righteousness. 14 But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil.
