15Who is the image of the invisible God, the firstborn of every creature: 16For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: 17And he is before all things, and by him all things consist. 18And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. 19For it pleased the Father that in him should all fulness dwell; 20And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven." (Colossians 1: 15-20)
Jesus holds all things together, and everything was made by Him and for Him. When the Bible writes "By Him all things consist", that word "consist" is better rendered "Hold".
He holds the whole world, and everything outside of this planet and far beyond, as well.
We can then trust that He is holding all things together for us, too.
Most importantly, He holds us in His hands:
"28And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. 29My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand. 30I and my Father are one." (John 10: 28-30)
Create this image in your mind:
Jesus holds you in His hands, his nail-pierced hands. Then imagine God the Father's hands holding Jesus' hands, and the Father's hands are also holding you.
You have double security, my friend, in knowing that God the Father is holding Jesus' hand and thus you. God the Father and God the Son have you in their grasp, and you will never fall!
