Hebrews 4:14-15

14Inasmuch then as we [believers] have a great High Priest who has [already ascended and] passed through the heavens, Jesus the Son of God, let us hold fast our confession [of faith and cling tenaciously to our absolute trust in Him as Savior].

15For we do not have a High Priest who is unable to sympathize and understand our weaknesses and temptations, but One who has been tempted [knowing exactly how it feels to be human] in every respect as we are, yet without [committing any] sin.
