Everyone is a misfit somewhere. When they are among unbelievers, believers are often misfits and vice versa. We should not be surprised when we notice that.
1 Peter 4:1: Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin; 2 That he no longer should live the rest of his time in the flesh to the lusts of men, but to the will of God. 3 For the time past of our life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and abominable idolatries: 4 Wherein they think it strange that ye run not with them to the same excess of riot, speaking evil of you:
2 Corinthians 6:14: Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? 15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? 16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people. 17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you, 18 And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.
There is only one way unbelievers and believers can be united. That is for the unbelievers to become believers. That should be our prayer for them. Genuine believers can never again become unbelievers. They can become one of us but we cannot become one of them.
Ephesians 2:11: Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands; 12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: 13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. 14 For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; 15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; 16 And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:
There are some individuals whose true nature and eternal destination we cannot know for certain. They seem to go back and forth from the church to the world. Some leave the church and stay away. I have known some who left the church and did not return until they were old. They walked in their miserable flesh for a long time.
2 Timothy 4:10: For Demas hath forsaken me, having loved this present world, and is departed unto Thessalonica; Crescens to Galatia, Titus unto Dalmatia.
The sad reality is that our flesh wants to be in the world. We must do what Paul did and keep our bodies under control.
1 Corinthians 9:27: But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
We must confess and forsake our sin so we will not be misfit believers in a church. I believe a misfit believer in a church is far and away better off than a misfit believer in the world.
