The Holy Spirit follows us year after year, as long as there is any possibility of a response on our part. He stayed with the people of Israel for centuries, bearing long with their rebellion and their stubborn hearts. It is a very difficult thing to walk away from the Holy Spirit. It is not easily accomplished. Because of His love.
Love never knows when it is enough.
Love does not give up easily. First Corinthians 13 tells us that love can outlast anything, and is, in fact, the one thing that still stands when all else has fallen. But the Holy Spirit loves as well. Now I beseech you, brethren, for the Lord Jesus Christ's sake, and for the love of the Spirit, that ye strive together with me in your prayers to God for me. Love is also an emotion, and this is yet another evidence of the personality of the Spirit of God.
