What the child’s hand is to the apple, that your faith is to the perfect salvation of Christ. The child’s hand does not make the apple, nor improve the apple, nor deserve the apple; it only takes; and faith is chosen by God to be the receiver of salvation, because it does not pretend to create salvation, nor to help in it, but is content humbly to receive it.
Charles Spurgeon (1834-1892)
