“The Son radiates God’s own glory and expresses the very character of God” (Hebrews 1:3a, NLT).
Like father, like son and a chip off the old block are two phrases we use to describe the similarity between fathers and sons. Dads love when their sons grow up to be responsible, mature men who took what they learned and put it into practice, and then pass it on to their sons.
In the case of God the Father and Jesus the Son, they are exactly alike. Jesus isn’t just a chip off the old block, but is one with him in everything. God’s glory is the Son’s glory and the character of God is seen in everything the Son does. Some wonder about the apparent disparity between the God we see in the Old Testament, who seems harsh and violent, and the gentle , forgiving Jesus in the New, but there is no difference: when we look at the Son, we see the Father. Like Father, like Son, like Spirit—in love, grace and mercy.
