Colossians 1:15 Who is the image of the invisible God, the Firstborn of all creation, Revelation 13:8 ...the book of life of the Lamb who was slain from the foundation of the world.
Some may wonder how Christ could be the firstborn of all creation since He was born less than two thousand years ago, not at the very beginning of creation. If we would understand this properly, we need to realize that with God there is no time element. For example, according to our estimate of time, Christ was crucified about two thousand years ago.
But Revelation 13:8 says that Christ was slain from the foundation of the world. Both are right. However, God's reckoning is much more important than ours.
In the eyes of God, Christ was crucified from the foundation of the world. In eternity, God foresaw the fall of man. Therefore, also in eternity, He made preparation for the accomplishment of redemption.
According to our sense of time, Christ was born in Bethlehem approximately two thousand years ago. But in the eyes of God, the Lord Jesus was born before the foundation of the world. If He was slain from the foundation of the world, certainly He must have been born before then.
Therefore, according to God's perspective in eternity, Christ was born in eternity past. This is the reason that, according to God's viewpoint, Christ has always been the first of all creatures. God foresaw the day that Christ would be born in a manger in Bethlehem.
Because Christ is the first among the creatures, we can say that as the all-inclusive One He is both the Creator and part of creation.
