He was ―tempted in all things as we are(Heb. 4:15).
―For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin. Hebrews 14:5
Infirmities (astheneia) means ―feebleness (of body or mind); by implication malady; moral frailty :- disease, infirmity, sickness, weakness.‖ Tempted (peirazo) means ―to test (object), i.e. endeavor, scrutinize, entice, discipline :- assay, examine, go about, prove, tempt (-er), try.
Jesus was fully (100%) human and fully (100%) God (know as the hypostatic union). Jesus was one person with two natures (human and divine). In his humanity, like all mankind, he was a dichotomy consisting of body and soul and, therefore, able to be touched by the weakness which so often touches us. Christ endured stress, pain, suffering, and sacrifice of an intensity that we will never face because he did not break. He stood strong against sin for us. He endured everything the world could throw at him.( Paul David Tripp, Instruments in the Redeemer‘s Hands, pg 167)
Jesus experienced physical frailty. He was born just like we were: He had a human body just like we do; He grew in wisdom and stature just like we do; He became tired just like we do; He became thirsty just like we do; He became hungry just like we do; He became physically weak just like we do; He physically died just like we do. Jesus experienced travail in his soul just like we do: ( Lk 2:7; Lk 2:40, 52; Jn 4:6; Mk 4:38; Jn 19:28; Matt 4:2; Lk 23:26; Lk 23:46 )
He experienced a troubled spirit; He experienced sorrow; He experienced anger and grief; He marveled; He wept; He prayed with loud cries and tears . Jesus experienced social rejection just like we do: He was forsaken by the Father; He was betrayed by one of the twelve; He was deserted by his disciples; He was not believed, even by his own family; He was reviled; He was falsely accused; He was spit upon and mocked. (Mk 15:34; Matt 26; Jn 6:65-67; Matt 13:55; Jn 7:5; Matt 27:39; Mk 15:32; Matt 26:59; Mk 10:34).
He was tempted in every respect as we are, yet without sin. When reviled he reviled not again; when left alone in his most needful hour he lovingly let them sleep; when slandered he said not a word but let his life speak for itself; when crucified he prayed father, forgive them, for they know not what they do; when dreading the cross he humbly submitted to the Father‘s will.( 1Pe 2:23; Matt 26:38-45; Jn 19:9-11; Lk 23:34; Lk 22:42).
We are joint-heirs with Christ; therefore, Scripture declares after suffering with him we will also be glorified with him. ―Jesus gained an ability to understand and help us in our temptations.-Because he himself has suffered and been tempted, he is able to help those who are tempted‘ (Heb 2:18).
He learned obedience thru what he suffered and so shall we.( Heb 5:8-9). ―Since Christ perfectly obeyed his Father even in the face of great suffering, so our obedience, trust, and patience in suffering more fully portray what Christ was like, and so bring more honor to him. It gives us great comfort to know that we are only experiencing what he has already experienced, and that he therefore understands what we are going through, and listens sympathetically to our prayers (Heb. 2:18; 4:15-16; 12:11- Wayne Grudem, Systematic Theology, pg 846).
Because of what he has done death, our last enemy, is swallowed up in victory and has lost its sting; because of what he has done we know we are not uniquely tested; because of what he has done we know he will not test us above our ability to endure it and will provide a way for us to escape.155 He left us an example that we should follow in his steps.―So this is the paradigm: purposeful suffering, leading to the experience of God‘s comfort, producing the ability to comfort others, resulting in a community of hope. (Paul David Tripp, Instruments in the Redeemer‘s Hands, pg 154).
