For it was the Father's good pleasure for all the fullness to dwell in Him,Colossians 1:19(NASB)
The simple gospel truth is easy for a child to understand, but for the rationally thinking man with his analytical mind, the simple gospel truth is the most complicated and abnormal concept to comprehend simply because it does not fall within the bounds of 'normal' human reasoning. But God's boundless and eternal mind is above the restricted limitations of man.
It was God's eternal plan that in Christ should all the fullness of the Godhead dwell - and the eternal plan of God was good - it was very good: "He is the image of the invisible God, the firstborn of all creation: by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones, or dominions, or rulers, or authorities - all things have been created through Him and for Him." Christ is the visible disclosure of the invisible God, begotten before the world was created, eternally co-existent with the Father, not a created being, of one substance with the Father, and it pleased the Father that in Him all the fullness of the Godhead dwelled, bodily.
"He is before all things, and in Him all things hold together." The plan of God was formed outside of time, space, mass, and matter, as well as being beyond the reach of human reasoning or man's analytical thoughts, for God purposed that Christ would be the federal head of a new creation, which is the Church, and that Christ would be the first to rise from the dead and in so doing, HE would become pre-eminent so that in everything HE might have the supremacy: "For it was the Father’s good pleasure for all the fullness to dwell in Him, and through Him to reconcile all things to Himself, whether things on earth or things in heaven, having made peace through the blood of His Cross."
The Cross and all it stands for is foolishness to the Gentiles and a stumbling-block to the Jews, but to those who believe the simple message of the Cross as a little child, with Christ as God's unique and perfect sacrifice, the Cross and all it stands for becomes the power of life, the wisdom of God, eternal salvation to the soul, and PEACE - a peace from God which passes all understanding to the man or woman that trust God's Word and believes the simple gospel of God's grace.
Heavenly Father, thank You for Your simple, sublime, gospel of grace, which has saved me from my sin and placed me in Christ, in Whom all fullness dwells. Help me to understand more of Your Word and to develop a simple, childlike faith, that is so pleasing to You. In Jesus' name I pray, AMEN.
