“The husband should fulfill his marital duty to his wife, and likewise the wife to her husband… Do not deprive each other except by mutual consent for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control” (1 Cor 7:3, 5).
Secondly, is kissing and romancing a sin in a relationship?
Kissing and romancing in a relationship is never a sin, it is just the nice and welcomed kind of communication. It is as we express love. Sex and when, depends on culture and customs and morals. But it belongs to life and nothing bad on that, when it is not abused as in promiscuity.
Keeping this in consideration, what does the Bible say about finding a soulmate?
The Bible tells Christians to “not be unequally yoked with unbelievers” (2 Cor. 6:14). And the idea here is that Christians and nonbelievers won’t share common goals in a relationship, especially one as close as marriage. So a potential “soulmate” should never be a non-Christian.
