For those who follow and serve the Lord, real Love is by faith.
There is such a tendency to think of Love as an emotion, but we know from I Corinthians 13 and the whole of God's Word that Love is more than strong feeling.
Often the experience of Love follows the obedience that makes Love possible. If Love does not take account of an evil done to it, or if it does not ever get puffed up, it has to be supernatural.
Certainly we have the precious experience of human love. When we walk in obedience to the word of God, there is a Love that is the result of refusing ungodly thought. Refusing gossip. Refusing to keep score. Putting others first.
No one ever arrives - not until heaven will we be perfect. There is no one who has it "all together." But there is One who gave Himself for us, and His Design is for us to walk in the Light and, to Love to the extent that we experience "rivers of living water. . ."
Have a ready smile. Be aware of your countenance. Do not engage in conversations that you know are unwise. Be ready with a word of encouragement. Even if you don't feel like it. Govern your thoughts.
It isn't fake. It is obedience.
