Whoever does the will of Our Father in heaven, is Christ’s brother, sister and mother.
(Matt 12:50) “For whoever does the will of My Father in heaven is My brother and sister and mother.”
This is why, Christians are referred as Brothers and Sisters in Christ. Also, throughout the letters in New Testament we see the brotherly love written over and over again.
(Heb 13:1) Let brotherly love continue.
(1Pet 2:17) Honor all [people.] Love the brotherhood. Fear God. Honor the king.
However, Bible also teaches to keep away from some people who call themselves as brothers in Christ. We are also told not even to pray for such people.
(Matt 18:15-17) ” Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. “But if he will not hear, take with you one or two more, that ‘by the mouth of two or three witnesses every word may be established.'”And if he refuses to hear them, tell [it] to the church. But if he refuses even to hear the church, let him be to you like a heathen and a tax collector.
John goes one step further to not even pray for a brother in Christ who is committing a sin that leads to death.
(1John 5:16-17) If anyone sees his brother sinning a sin [which does] not lead to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death. I do not say that he should pray about that. All unrighteousness is sin, and there is sin not leading to death.
The question is, are you obeying the Bible in getting away from name-Christians? Or are you yourself a name-Christian? Repent!
