He came “Not to be served, but to serve, and to give His life a ransom for many” (Mathew 20:28). He came to offer His own perfect life as a sacrifice for undeserving sinners. He achieved that by entering the world as a helpless infant, living a sinless life of perfect obedience under the rigorous demands of Moses’ law (Galatians 4:4) while still embodying all the perfections of His Divine holiness. 
The scriptures reveal that even though He was subject to normal human vulnerabilities such as hunger, thirst, and weariness (Hebrews 4:15), He was triumphant in resisting every temptation common to us all (Hebrews 2:18). 
But the greatest display of His unconditional love was made clear when He set aside His glory and humbled Himself, suffering the death of one of the most excruciating methods of capital punishment ever created in human history. 
And as He promised, on the third day following His death, He rose from the dead, demonstrating His authority and power over life, death, and the forces of hell. 

This is the gospel message that Jesus’ redemptive work of the cross will save all His people who have put their faith in Him and confessed Him as Lord. 
On the cross, He bore our sin and suffered the punishment for the guilt that was due to us. Thus He atoned for our sins in full, covering them graciously with His own perfect righteousness (2 Corinthians 5:21) through which we can stand before God fully justified.
