Love
One of the Fruits of the Holy Spirit. A visible attribute of a true Christian life as found in Galatians 5:22-23.

Agape love denotes an undefeatable benevolence and unconquerable goodwill that always seeks the highest of the other, no matter what he does. It is the self-giving love that gives freely without asking anything in return, and does not consider the worth of its object.
"And this is love: that we walk in obedience to his commands. As you have heard from the beginning, his command is that you walk in love." 2 John 1:6
