The Covenant of Redemption in Jesus' High Priestly Prayer

"I am praying for them. I am not praying for the world but for those whom you have given me, for they are yours." (John 17:9 ESV) 

"Therefore I endure everything for the sake of the elect, that they also may obtain the salvation that is in Christ Jesus with eternal glory." (2 Tim 2:10 ESV)

"For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin." (Heb 4:15 ESV)

According to the Covenant of Redemption, the Father has given the elect to the Son as a reward for His perfect obedience.
