Scripture on dating and marriage
This liking involves a "friendship kind of" affection based often on personality and common likes and interests.
A second kind of relationship is “brother-sister in Christ.” If we have accepted Christ as our Savior we have become children of God.
God is our Father and other Christians are our brothers and sisters in Christ. Our Father deeply loves and desires that we show love to each other, that is seek each other's highest spiritual good.
1 Jn.3: 1 says, "How great is the love the Father has lavished on us that we should be called children of God! " Gal.5: 13 says, “Rather serve one another in love.” Heb.10: 24 says, “Let us consider how we may spur one another on toward love and good deeds.” God desires that we serve one another in love by giving of ourselves to help each other grow in Christ as fellow-believers.
Friendship and marriage have a third characteristic - affection and attraction, although the nature of the affection and attraction is different.
Song of Songs -11 says "How delightful is your love my sister, my bride!
