Surely, if God could be revealed through words alone then God’s incarnation would not have been necessary.
That the Word become meat and bones (John 1:14) carries the implication that words are not enough for transmitting the way, the truth and the life.
I think then, the wordiness of the Evangelicalism needs to be questioned. The medium is intimately tided to the message; it has always been God’s intention that the communication of grace proceed from communities of grace.
Therefore, let us love our enemies in action and truth … not merely in words and “in our hearts”.
