Hebrews 10:24 And let us consider one another to provoke unto love and to good works.
If you intend to make love a habit, you must develop the habit of loving people with your words. Your fleshly {lower} nature point out flaws, weaknesses, and failures. it seems to feed on the negatives in life. it sees and magnifies all that is wrong with people and things. But the Bible says you are to overcome evil with good {see Romans 12:21}
Walking in the Spirit --- CONTINUALLY following the leading, guiding and working of the Holy Spirit through your own spirit instead of being led by your emotions ---- requires being positive.
It is easy to find something wrong with everyone. But love does not expose faults -- it covers them. Ask God to help you share His love with others.
