"For the grace of God has appeared that offers salvation to all people."
Just how important is grace? Grace (charis) occurs 156 times in the N.T. J.I. Packer, the well respected British theologian and author, says, "In the New Testament, ‘grace' is a word of central importance - the keyword, in fact, of Christianity. The thought of grace is the key that unlocks the New Testament; and it is the only key that does so. However well we may know the New Testament, we cannot get inside its meaning till we know something of what grace is."
Whether we realize it or not, the entire Bible centers on grace and reveals grace, for grace is the way our God operates. But grace is counter-intuitive to all human beings including Christians, who function on the basis of the law, which is blessing and reward based on merit, not grace.
