1:17 consist. The Greek word translated “consist” is sunistano, from which we get “sustain.” The things created by Christ are now being sustained, or conserved, or held together, by Him. He is “upholding all things by the word of His power” (Hebrews 1:3). “In Him we live, and move, and have our being” (Acts 17:28). The most basic of all scientific principles is implied in these two verses (Colossians 1:16-17), that is, the principle of conservation of mass/energy, or “all things.” According to this principle, nothing is now being either created or annihilated—only conserved, as far as quantity is concerned. One state of matter can be changed to another (e.g., liquid to solid); one type of energy can be converted to another (e.g., electrical energy to light energy); and under some conditions, matter and energy can be interchanged (e.g., nuclear fission); but the total quantity of mass/energy is always conserved. This law—also called the First Law of Thermodynamics—is the best-proved law of science, but science cannot tell us why it is true. The reason nothing is now being created is because Christ created all things in the past. The reason why nothing is now being annihilated is because all things are now being sustained by Him. If it were not so, the “binding energy” of the atom, which holds its structure together, would collapse, and the whole universe would disintegrate into chaos.
