"Consequently, he could let his external life change without internal distress because he was rooted and grounded in God. Most of us are not consistent spiritually because we are more concerned about being consistent externally. In the external expression of things, Paul lived in the basement, while his critics lived on the upper level. And these two levels do not begin to touch each other. But Paul’s consistency was down deep in the fundamentals. The great basis of his consistency was the agony of God in the redemption of the world, namely, the Cross of Christ."
"Rooted and grounded in God" — what a wonderful phrase, right from the pen of the inspired Evangelist:
"As ye have therefore received Christ Jesus the Lord, so walk ye in him:
"Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving. " (Colossians 2: 6-7)
"Our walk" is based on how "rooted" we are — IN CHRIST. He leads us as we grow in grace and knowledge of Him!
We walk in the eternal glory of God's indwelling power through the Holy Spirit, and we can boldly claim this through the redeeming Finished Work of the Cross of Jesus Christ!
