All things begin with God - “In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made” (John 1:1). All things that follow stream from his eternal purpose which will ultimately be accomplished.
Our Lord Jesus Christ did not just enter into the scheme of things in time, he is the eternal Son of God from everlasting which was manifest in the flesh, in time. Neither God nor his Son has a beginning, yet all things have their beginning in the Godhead. This Biblical truth is the quintessence of all truth. If this be not so then Divinity has no real meaning, value or merit. I believe that is why, by Divine inspiration, Holy Writ begins thusly - “In the beginning God.” In respect to this revelation of God in Christ the child of God has great interest, primarily because in him who is the beginning of all things our salvation originates or has it’s beginning - “But of him (God) are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption” (1 Cor. 1:30).
If it be so that the beginning of our salvation is Christ and is in Christ, who is the Alpha, then all our salvation to the end is in him who is the Omega as well. Not only was he in the beginning, he is the beginning! And He never changes! - “Jesus Christ the same yesterday, and today, and forever” (Heb. 13:8). The word “beginning” is strictly to accommodate us mere mortals because with God all things are in the eternal present.
The way we, by faith, see this great and wonderful mystery revealed is that in the beginning, before the foundation of the world, God the Father chose his people in Christ unto salvation. In time the Son of God was manifest in the flesh to begin and accomplish eternal redemption for us. In time the Lord Jesus Christ in the Person of His blessed Spirit begun a good work in us and will perform it unto perfection. Dear reader, what we experience now and will experience in the future, as the children of God, is a work finished from the beginning - “For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world” (Heb. 4:3).
In this context our great comfort is twofold. 1.) God never begins anything that he doesn’t finish. 2.) All that he does for his people is in Christ, who is the beginning.
You agnostics perish with your vain thoughts. . . You who know Christ rejoice with great joy that all things are in him.
