The heart of The Gospel, is essentially, that we are loved;
By God, and by Yeshua;
The term "Love each other as I have loved you",
and Isaiah 53 come to mind:

"...He is pierced for our transgressions, bruised for our iniquities, The discipline of our peace [is] on Him, And by His scourging we are healed.
All of us, like sheep, have wandered, Man has turned to his own way, And YHWH has laid on Him the punishment of us all.  It has been exacted, and He has answered, And He does not open His mouth, He is brought as a lamb to the slaughter, And as a sheep before its shearers is silent, So He does not open His mouth.  By restraint and by judgment He has been taken, And of His generation who meditates, That He has been cut off from the land of the living? He is plagued by the transgression of My people, And He appoints His grave with the wicked, And with the rich at His death, Because He has done no violence, Nor [is] deceit in His mouth.  And YHWH has delighted to crush Him, He has made Him sick; If His soul makes an offering for guilt, He sees [His] seed—He prolongs [His] days, And the pleasure of YHWH prospers in His hand.  Of the labor of His soul He sees—He is satisfied, Through His knowledge My Righteous Servant gives righteousness to many, And He bears their iniquities.  Therefore I give a portion to Him among the many, And He apportions spoil with the mighty, Because that He exposed His soul to death, And He was numbered with transgressors, And He has borne the sin of many, And He intercedes for transgressors."
(Verses 5-12 LSV )

John 15:13 (ESV)
