JESUS - Hebrews 4:14

Therefore, since we have a great high priest who has ascended into heaven, Jesus the Son of God, let us hold firmly to the faith we profess.

Therefore, since we have a great high priest 
Hebrews 2:17-18  For this reason he had to be made like them, fully human 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. Because he himself suffered when he was tempted, he is able to help those who are being tempted.

who has ascended into heaven 
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 our forerunner, Jesus, has entered on our behalf. He has become a high priest forever, in the order of Melchizedek.
Hebrews 8:1-2  Now the main 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 a mere human being.
Hebrews 9:24  For Christ did not enter a sanctuary made with human hands that was only a copy of the true one; he entered heaven itself, now to appear for us in God's presence.

Jesus, the Son of God 
Matthew 3:16-17  As soon as Jesus was baptized, he went up out of the water. At that moment heaven was opened, and he saw the Spirit of God descending like a dove and alighting on him. And a voice from heaven said, "This is my Son, whom I love; with him I am well pleased."
John 20:30-31  Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.

let us hold firmly to the faith we profess 
Hebrews 2:1  We must pay the most careful attention, therefore, to what we have heard, so that we do not drift away.
Hebrews 3:6  But Christ is faithful as the Son over God's house. And we are his house, if indeed we hold firmly to our confidence and the hope in which we glory.
Hebrews 3:14  We have come to share in Christ, if indeed we hold our original conviction firmly to the very end.
