The most important thing about Christ is that he fully vindicates Jehovah God's right to rule over mankind,clearing his name of all reproach heaped upon it by Satan's slander and by mankind's rebellion by himself proving faithful even to death. (Genesis 3:15 Job 1:7-12,22 Matthew 6:9,10 Psalms 83:18)
Also,he provides the value of his ransom sacrifice to his father on our behalf so that faithful people can be redeemed to God and have the opportunity to enjoy everlasting life on a paradise earth under God's kingdom rule. (John 3:16 1 Corinthians 15:22-28 Revelation 7:14-17 20:6 21:3,4 Psalms 37:11,29)
Then he will demonstrate fully his love for mankind when his God given rulership of the earth brings unending blessings to obedient ones of mankind - Daniel 7:14 Job 14:15b Psalm 37+ 72 1 John 5:3 Revelation 11:15.
