“If we love one another God abides in us, and his love has been perfected in us.”
I remember a Christian once telling me “I tried so hard to love that person, that irritating Christian at church, and I failed and failed and failed.
In the end I gave up and prayed, ‘Lord, you will have to do it in me. You will have to love her through me.’
Once I started to trust entirely on Christ, my whole attitude to her changed and I found a love for her in me.”
That is how it works. We just have to depend on the Lord and say “Lord, I can’t do this. I can’t love that person. He just annoys me. He so irritates me. You are going to have to do this in me.”
And he will. He has said, “Without me you can do nothing.” (v.5) There must be total dependence on the power of God.
