one-taken from amongst men? He does not glorify Himself, genethenai (to be made). But He who said, Thou art My Son, this day have I (emphatically) ego (I) begotten Thee. Though a man yet He is not simply taken from amongst men as such but God says of Him (even as a man) I have begotten Thee.
This qualified Him as to calling in contrast with glorifying Himself but also in contrast with mere human priests, then He is constituted and owned priest by God as in the 110th Psalm. This makes the fifth verse plain. Compare Heb. 7:2828For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore. (Hebrews 7:28).
Note in 1 Thess. 5:88But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation. (1 Thessalonians 5:8) we have the three great principles of Christian life-faith, hope and love. Evidently these three were pretty settled and constantly in the Apostle's mind; we have them in chapter 1:3. In chapter 5:8 it is hardly against enemies though it supposes them, but more in the way of their watchfulness, that is, a heart right with God as to its state than actual conflict with enemies.
In Ephesians we are in conflict with enemies and have to be such and such to succeed and wield the sword successfully. Hence the breastplate is practical righteousness, which we must have to contend effectually with Satan. In Eph. 6, after the whole subjective state is gone through before using the sword, we have the helmet of salvation-a deliverance that belongs to us which we enjoy and enables us to use the sword, coming after the shield of faith-entire confidence in God. In Thessalonians it is one of the elements of our life with God in its final result as a matter of hope, the active energy of the life with God in faith, love and hope in sobriety of walk in the midst of dangers or enemies down here.
