It means talking, sharing thoughts and problems. Like a garden it grows better, the more the weeds are pulled out and the more loving care is given. It is the ideal setting for bringing up children. No one should rush into marriage. The other's character, interests, behaviour, and family life should be carefully considered first.
Single life is also quite normal, and can be very happy and fulfilling.
It is far better to be free, single, and have many friends, than be married to the wrong person. It is giving as well as receiving. More than anything else, marriage can become successful with God's help. If we let God change us, if we bring Him into our marriage, if we pray to Him, sex and marriage can become brilliant. The Greek words in the Bible 'pornos' and 'porneia' refer to sex outside marriage.
