God is love. John said that twice in that passage of his first letter and it sets the final bounds to human destiny. If a man loves, that is the evidence of his union with God. If a man loves his brother, the invisible God is made visible in that act. That is the last word that can be said-for time and eternity. Love is selflessness. The last rung of the ladder of attainment has been climbed. God is total disinterestedness in what might be to His own advantage. When it speaks of Him vindicating His own righteousness, giving pre-eminence to His own glory, that is not because of what He gets out of it: it is because only in the sharing of His perfections can His creatures attain theirs. It is for their sakes, for the universe of His creation, that He maintains the inviolability of His Throne.
Love must sometimes be wrathful, appear self-interested and demanding, and appear to maintain its own rights and dignity. Only love can safely do that, just because of its total detachment from self-interest. Can we imagine a Being whose sole occupation for the ages of the ages is to carry the burdens and provide for the needs of others, and when those burdens and needs add up to those of the whole creation? And when the only human race we know of, made to be His peculiar treasure, hates Him, rejects Him, takes all and gives nothing, not even thanks, and often denies His existence? And His answer is to set to work to win them back by giving His life for them!
