My strength cannot find its source in my self. It has to find strength that is like gravity or light or heat. If my ability to stand or to be settled or be committed is from within me, it will be relative in its ability to be maintained. It will be questionable in its ability to discern truth. It will not work in every circumstance.
If, instead, my strength comes from the Spirit of Jesus, it has potential for being unfailing, unerring, unswerving, unbreakable, and trustworthy.
For this reason I bow my knees before the Father from whom every family in heaven and on earth is named. I pray that He may grant you, according to the riches of His glory, to be strengthened with power through His Spirit in the inner man, and that the Messiah may dwell in your hearts through faith. I pray that you, being rooted and firmly established in love, may be able to comprehend with all the saints what is the length and width, height and depth of God’s love, and to know the Messiah’s love that surpasses knowledge, so you may be filled with all the fullness of God.
