Men who know their God are before anything else men who pray, and the first point where their zeal and energy for God's glory come to expression is in their prayers. If there is little energy for such prayer, and little consequent practice of it, this is a sure sign that as yet we scarcely know our God.
J. I. PackerMoreover, the whole purpose of God's mighty acts is to bring man to know Him by faith; and Scripture knows no foundation for faith but the spoken word of God, inviting our trust in Him on the basis of what He has done for us.
J. I. PackerIf you want to judge how well a person understands Christianity, find out how much he makes of the thought of being God's child, and having God as his Father. If this is not the thought that prompts and controls his worship and prayers and his whole outlook on life, it means that he does not understand Christianity very well at all.
J. I. PackerIt has been said that in the New Testament doctrine is grace; and ethics is gratitude; and something is wrong with any form of Christianity in which, experimentally and practically, this saying is not being verified. Those who suppose that the doctrine of God's grace tends to encourage moral laxity are simply showing that, in the most literal sense, they do not know what they are talking about. For love awakens love in return; and love, once awakened, desires to give pleasure.
J. I. Packer
