“That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive; But speaking the truth in love, may grow up into him in all things, which is the head, even Christ:” - Ephesians 4:14, 15.
The first quality of good communication is truthfulness. There cannot be good communication unless there is this desire on both parties to be truthful. There is no better advice anywhere for mate-to-mate, parent-to-parent, friend-to-friend, or any other type of communication than, “Speak the truth in love” If more of us practise this, we would see ourselves grow in Christ-like virtues within the context of marriage. Speaking the truth, sharing with openness and freedom what is on one's heart, is one of the qualities essential for good communication. One who has love for his neighbour will know how to handle anger properly. Ephesians 4:26 says, “Be ye angry, and sin not: let not the sun go down upon your wrath.” There are two ways of handling anger incorrectly. We do wrong and we sin when we handle anger by losing our temper (“blowing up”). That is suggested by the last word in verse 26, wrath. There is another wrong way of handling anger and that is by quietly pouting (“clamming up”, refusing to talk). That is also suggested in verse 26 when it says, “let not the sun go down upon your wrath.” When there is irritation and anger inside, the problem should be talked out. Communicate! Don't let it smoulder. Don't suppress it. Don't put off discussing it. Deal with it, and deal with it before sundown as Apostle Paul says in the text under reference. The handling of anger biblically is vital for physical, mental, emotional, and spiritual health.
