Nothing grieves our Heavenly Father quite so much as a cool assessment of His only Son. He takes it very personally indeed. It makes Him angry-- Good and angry, mind you, but angry none the less.
The Triune nature of God renders this wrath other-centered and God-centered all at the same time. God's emotions, therefore, are never self-centered in the toxic and destructive way yours and mine often are.
The Father is full of indignation that people think so little of His lovely Son, the Son is enraged that men slight the glory of His ever Blessed Father, and the Spirit is grieved beyond measure that men put so little stock by the Father and the Son. What base ingratitude to think so little of God-- the author of our every happiness, the giver of our every breath, the ruler of our every moment, the limiter of our every earthly pang, the forgiver of our every sin, and the present restrainer of our true deserts (Psalm 103:10).
For the Christian, lukewarmness to Jesus is an especially staggering incongruity. We must all hang our heads in shame....
Back in Mississippi, in every visitors' book he ever signs, a good friend has the habit of leaving 1Cor 16:22 as his calling card. At times, I have to confess, I thought it a bit quirky-- you might even deem it obnoxious! But this is, you remember, Paul's conclusion after writing his great 15th chapter to the Corinthians. Glorious verses, several of which inspired Handel's great Christmas oratorio, the Messiah. Writing to the Church in Laodicea, Jesus is no less hard hitting when it comes to addressing spiritually lethargic souls (Rev. 3:1-6).
O, may God help us to live without such an epitaph appended to our religiosity. May God fill our hearts with love for his Son this Christmas time. Love that would constrain and command all the redeemed energies of our souls for the worship and service of our Triune God.
