For the Father loves the son and shows him all that he does. Yes, to your amazement he will show him even greater things than these.
The word for love here is 'phileo' not 'agape' as it was in 3:35. It is 'brotherly' or 'family' love. This stresses the relationship between father and son. Here we perceive a mystery that defeats the Muslims. How can one God be a family? Does it not transgress the tenet that there is but one God? Obviously not. When we say that God is love, how could that be before the creation when there was no-one to love? The Father loved the Son and the Son loved the Father and both loved the Holy Spirit.
What were the greater things? What but salvation?
