And let us consider and give attentive, continuous care to watching over one another, studying how we may stir up (stimulate and incite) to love and helpful deeds and noble activities.
– Hebrews 10:24

If we intend to make love a habit, then we must develop the habit of loving people with our words. The fleshly (lower, sensual) nature points 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 in Romans 12:21 that we are to overcome evil with good.

Walking in the Spirit (continually following the prompting or leading, guiding, and working of the Holy Spirit through our own spirit instead of being led by our emotions) requires being positive. God is positive, and in order to walk with Him we must agree with Him (see Amos 3:3).

It is easy to find something wrong with everyone, but love covers a multitude of sins: Above all things have intense and unfailing love for one another, for love covers a multitude of sins [forgives and disregards the offenses of others]. (1 Peter 4:8) Love does not expose faults; it covers them.
