Hebrews 11:3 Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear. 

‘Worlds’ [Greek: aion and ages] age – a period of time whether long or short. Translated “world” (1:2; Matt. 12:32; 13:39); “age” (Eph. 2:7; Col. 1:26); “course” (Eph. 2:2); and other ways. Here it means Christ was the agent in planning the ages and making God’s plan for man. In this sense, He is the everlasting Father (Isa. 9:6). He not only planned the ages but all creations (Col. 1:15-18; John 1:3; Eph. 3:9).

Colossians 1:15 calls Christ Jesus the firstborn of every creature. He is the firstborn of creation. The Greek word prototokos means firstborn (Col. 1:15, 18; Matt. 1:25; Luke 2:7; Rom. 8:29; Heb. 11:28; 12:23) and first-begotten (Heb. 1:6; Rev. 1:5). It is used of Jesus the firstborn of Mary (Matt. 1:25; Luke 2:7) and of the firstborn of Egyptians (Heb. 11:28). It means the first one born in the family. It must also be understood in this literal sense in connection with Jesus being the firstborn in God’s family. However, Sonship in this case refers to His humanity and not to deity. Jesus took a human body to redeem (Php. 2:5-11; Isa. 7:14; 9:6). It was when God had a Son through Mary (Matt. 1:18-25; Luke 1:35; John 1:14). This happened on a certain day: “This day have I begotten thee” (Heb. 1:5-7). Therefore, we cannot say that God had a Son before this time. This proves that sonship in connection with God had to refer to humanity and not to deity.

With these facts it is clear in what sense Jesus is “the firstborn of every creature” or of all creation (Col. 1:15), and “the firstborn among many brethren” (Rom. 8:29). All creation came into existence by creative acts, not by a begetting as in the case of Jesus. Even the “many brethren” are not begotten in the sense Jesus was by the Holy Spirit. They were begotten by people, not by God, and were thus brought into the human family, not the family of God. The only way one gets into God’s family is by adoption (Rom. 8:14-16; Gal. 4:5-6; Eph. 1:5). Jesus is the only begotten Son … the first of all creatures to be begotten of God, the only one of all beings begotten of God, the first and only one of the family of adopted and “created” brethren begotten of God (Eph. 4:24; Col. 3:10), the first-begotten of or from the dead, and the firstfruit of the resurrection of all men (1Cor. 15:23-33; Col. 1:18; Rev. 1:5). Christians are the called-out people of the one who is the firstborn (Heb. 12:23). Adam and angels were by creation, not by begetting (Luke 3:38; Gen. 6:1-4; Job 1:6; 38:4-7).

‘Were framed’ [Greek: katartizo] The ages were planned by the Word of God and the things that are now seen were not made of existing material. Both the ages and dispensations as well as the material creations are referred to here (Gen. 1:1; Heb. 1:2).
