The law of love is the law of life.
God is love. He created everything to operate in harmony with this law of love.
We have photosynthesis, the water cycle, even the circle of life. Everything in each has a purpose and works for the rest of the cycle. To violate the law of love causes a snowball effect or domino effect. Christ gave his life and gave with a greater love than anyone could ever have. He caused a domino effect of a greater kind. He taught us to love without judgment. He taught us to love for healing. He taught us love is the greatest power of all.
True love isn't comfortable but it means doing what is best for others. Love is doing what is right.
And so we know and rely on the love God has for us. God is love. Whoever lives in love lives in God, and God in them.
1 John 4:16
