All that we need to obtain Salvation is found in Jesus

Hebrews 2:1-6,Therefore we must give the more earnest heed to the things which we have heard, lest we drift away, for if the word spoken through angels proved steadfast, and every transgressions and disobedience received a just reward; How shall we escape if we neglect so great a Salvation, which at the first began to be spoken by the Lord. And was Confirmed to us by those who heard, Him. [Jesus]  God also bearing them witness, both with signs and wonders, and with various Miracles, and gifts of the holy Spirit, according to His own will.[Because Christ have to die for human, He put on human flesh, and took on human Nature, so that He could die on the cross for our sin. He did not died for angels; So He did not took on angels Nature. For Christ to endured Suffering on earth, died buried, and Rose again to free us from Sin, and bring us back to God, He has to be a Holy perfect Leader, Who walked before God on this earth with perfect Obedience. In all His Sufferings, and temptations, He remain Sinless. So He is able to provide Strength, and encouragement to those who need it.

Hebrews 2:7-10, [God] You have made Him [Christ] a little lower than the angels; you have crowned Him with glory and honor, and set Him over the works of your hands: You have put all things in subjection  under His feet. He [God] left nothing that was not put under Him. [Jesus] But we see Jesus, Who was made a little lower than the angels for the Suffering of death, crowned with glory and honor; that He by the grace of God should taste death for every man. For it was fitting for Him, for whom are all things, in bringing many sons to glory to make the captain of their salvation perfect through sufferings. For both He who sanctifies and those who are being sanctified are all of one, for which reason He is not ashamed to call them brethren, saying: I will declare your name to My brethren; Therefore, in all things, He had to be made like His brethren, that He might be a merciful and faithful High Priest in things pertaining to God, to make propitiation for the sins of the people.   For in that He Himself has Suffered, being tempted, He is able to aid those who are tempted.
