Peter Leithart notes that many Christians see God the Father as this cold, harsh, angry God who needs to be appeased by the kind, loving Jesus. However, this separates what the Scriptures have joined together. In the Bible, Jesus is God. There are not two gods, one angry, one loving. There is one God. He is love. This love is seen as the Father sends the Son, the Son dies for his people, and the Spirit is poured out so that the people might love each other.
“You want to know what God is like, really? Take a look at the gospel. If you have seen Jesus, if you have seen him in the manger, seen him tempted in the wilderness, seen him passionately fighting the Pharisees who oppress his people, freely offering himself on the cross, powerfully rising again from the dead-when you have seen all this, you have seen God who is love. Jesus did all of this out of his love for us, and because his Father sent him out of love. You want to see the love of God, read about Jesus. For whoever has seen Jesus has seen the Father.” (From Behind the Veil, p. 151)
“Being in the light that is the life of the New Covenant requires more than a profession of faith. Several times John contrasts what people say with what is actually the case (I John 1:6-7, 2:10). We do not have fellowship with Christ merely by saying we have fellowship with him. We must not only say we have fellowship with Light, we must actually walk in the light, especially by living in fellowship and love with our brothers in the church.” (Peter Liethart, From Behind the Veil, p. 52)
How many of us have thought, if only I had been able to walk with Jesus to see his risen body, then I wouldn’t have to trust in anything but my own eyes. Dr. Leithart effectively counters this argument in his commentary on I John.
“We moderns think unity is easy. We only have to sit down and talk and everyone will rise from the conference table filled with the glow of love and peace. The Bible knows this is a delusion. Unity is costly, achieved only by the anguish of crucifixion. Unity seems easy for us only because of the blood of Jesus, and the blood of many martyrs since.” (Peter Leithart, Behind the Veil, p. 34-35)
