Hebrews 4:14-16

Therefore, since we have a great high priest who has gone through the heavens, Jesus the Son of God, let us hold firmly to the faith we profess. For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we are--yet with out sin. Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need.

Therefore, since we have a great high priest
Hebrews 2:17 For this reason he had to be made like his brothers in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people.

who has gone through the heavens
Hebrews 6:19-20 We have this hope as an anchor for the soul, firm and secure. It enters the inner sanctuary behind the curtain, where Jesus, who went before us, has entered on our behalf. He has become a high priest forever, in the order of Melchizedek.
Hebrews 8:1-2 The point of what we are saying is this: We do have such a high priest, who sat down at the right hand of the throne of the Majesty in heaven, and who serves in the sanctuary, the true tabernacle set up by the Lord, not by man.
Hebrews 9:24 For Christ did not enter a man-made sanctuary that was only a copy of the true one; he entered heaven itself, now to appear for us in God's presence.

let us hold firmly to the faith we profess
Hebrews 3:1 Therefore, holy brothers, who share in the heavenly calling, fix your thoughts on Jesus, the apostle and high priest whom we confess.

but we have one who has been tempted in every way, just as we are
Hebrews 2:18 Because he himself suffered when he was tempted, he is able to help those who are being tempted.

yet was without sin
2 Corinthians 5:21 God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.

Let us approach
Hebrews 7:18-19 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.

the throne of grace with confidence
Ephesians 3:12 In him and through faith in him we may approach God with freedom and confidence.
