John 6:37–40 proclaims that Jesus came down from heaven on a divine rescue

mission—not merely to give an example or offer the possibility of salvation, but to actually save

sinners with certainty and secure their eternal life. We all long for comfort but will we find it in

human effort or in Christ’s sovereign grace? True assurance cannot be found in our own attempts

to reform but only in Jesus’ promise that he will never lose those the Father has given him and will

raise them up on the last day. Therefore, the heart of Christmas is the comfort Christ brings to

undeserving sinners, offering full confidence of salvation to all who trust in him.
