Cute? I am not even attempting to be cute or funny. I am speaking the truth according to the WORD OF THE LORD. If you see it as being cute or funny then you have a serious problem that needs to be rectified according to the that Word which is the whole BIBLE. I am not going to waste my time in this thread since individuals only want to justify their judgmental ways and legalistic doctrine which does not line up with the WORD OF THE LORD and because it doesn't line up with that word it is not true and is false teaching.
Hebrews speaks of 'the church of the firstborn which are written in heaven'.
Making sure we are in the true church involves believing in the Lord Jesus, Who died at the Cross for sinners. (Not on being dunked by the 'correct' church.)
