Perseverance is the gift of God, which he does not lavish promiscuously on all, but imparts to whom he pleases. If it is asked how the difference arises--why some steadily persevere, and others prove deficient in steadfastness, we can give no other reason than that the Lord, by his mighty power, strengthens and sustains the former, so that they perish not, while he does not furnish the same assistance to the latter, but leaves them to be monuments of instability.
