You obeyed the truth, and your souls were made pure. Now you sincerely love each other. But you must keep on loving with all your heart.
(1 Peter 1:22 CEV)
God expects us to love people (especially those from His family) from the heart. Since this is a divine command, the enemy will do everything in his power to destroy this love. It becomes easy to love people when they’re nice to us, but difficult when they hurt us. It takes supernatural power to love people despite their flaws. God is love, and only He can enable us to love others at all times and from the heart. Ask Him to love others through you.
God enables us to love others with unconditional love.
