If we love only those who love us, this world would be full of hate because everyone will be waiting to be loved before loving.
Love is a seed. The laws of the spiritual and the natural agree on the fact that you only harvest the seeds that you plant.
The Bible even tells us the reason why the early Christians loved God and others. “We love because God first loved us”-1 John 4:19.
If God would not violate this principle, why do you suppose that you can? Are you stronger than God? If you always feel unloved, unwanted and lonely, it may very well be that you are waiting to be loved rather than sowing seeds of love.
Remember, “God cannot be mocked. A man reaps what he sows”-Galatians 6:7.
