Hebrews 4:15
For we have not an high priest which can not be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
Imagine meeting the new politician who is to represent your district or neighborhood only to discover that he is not familiar with your neighborhood’s needs and problems. You will wonder, “Can this guy really represent us? Does he know anything about our living conditions? Is he familiar with the various challenges that families here are facing? Can he help me get my child into one of the schools here?” I am sure that you would prefer someone who truly understands your challenges to represent you!
In the same way, I am so glad that right now at the Father’s right hand, we have someone who came as a Man to redeem us, and who fully understands what man goes through. When Jesus walked on earth, He went through every human emotion so that He could identify with us in all points. Jesus is God, but He is in the Father’s presence as a Man, representing us.
My friend, you may feel that no one understands your struggles. Listen, while this may be true of man, it is not true of Jesus. He knows exactly what you are going through and He can sympathize with your weaknesses because He was “in all points tempted as we are, yet without sin”.
None of us have been tempted in all points. But God allowed Jesus to be tempted in all points so that He can understand and identify with the struggles of every single person on this earth. He can be touched by our humanity—our weaknesses, tears, disappointments, griefs...all points!
There is no trial, difficulty, challenge or temptation that you face that Jesus cannot identify with. My friend, the moment you go through it, right there and then, He feels it too. That is the kind of representative you have in Jesus! That is the love of God so that you will draw near to His throne of grace (not judgment) to find mercy and grace in time of need! (Hebrews 4:15–16)
