Haven’t we heard many times from some Christians, “I am a Christian but premarital sex and cohabitation is okay. That is love you know!” We cannot say, “I am a Christian because I believe in love but I don’t believe in the church stand on marriage.” That is not Christian faith; that is Your Faith. If we are Christians, we believe in “everything” it teaches and not just “what we think“ we can believe in.
Our Christian faith is wholesale not retail! We cannot pick and choose what we like, it’s either we take it or leave it. We either believe in it as whole or nothing at all.
Jesus teaching can be hard to swallow at times, but that is what it is.
