God has set before you an open door which no man has a right or power to shut. If you should be shut out, it will be by your own unbelief, and not for want of a warrant to come. Enter, then, without delay or hesitation. None can less afford to delay than the aged sinner. Now is the time. Now or never. You have, as it were, one foot already in the grave. Your opportunities will soon be over. Strive, then, I entreat you, to enter in at the strait gate.

Archibald Alexander (Theologian, 1772 -1851)
