SALVATION Hebrews 2:10

In bringing many sons and daughters to glory, it was fitting that God, for whom and through whom everything exists, should make the pioneer of their salvation perfect through what he suffered. 

 it was fitting that God, for whom and through whom everything exists 
Romans 11:36  For from him and through him and for him are all things. To him be the glory forever! Amen.

should make the pioneer of their salvation perfect through what he suffered 
Luke 24:25-27  He said to them, "How foolish you are, slow to believe all that the prophets have spoken! Did not the Messiah have to suffer these things and then enter his glory?" And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself.
Hebrews 5:8-10  Son though he was, he learned obedience from what he suffered and, once made perfect, he became the source of eternal salvation for all who obey him and was designated by God to be high priest in the order of Melchizedek.
Hebrews 7:28  For the law appoints as high priests men in all their weakness; but the oath, which came after the law, appointed the Son, who has been made perfect forever.
Hebrews 7:18-22  The former regulation is set aside because it was weak and useless (for the law made nothing perfect), and a better hope is introduced, by which we draw near to God. And it was not without an oath! Others became priests without any oath, but he became a priest with an oath when God said to him: "The LORD has sworn and will not change his mind: 'You are a priest forever.' " [Psalm 110:4] Because of this oath, Jesus has become the guarantor of a better covenant.
