IV. Timely repentance gains God's merciful consideration
Our state of peace, therefore, dearly-beloved, has its dangers, and it is vain for those who do not withstand vicious desires to feel secure of the liberty which is the privilege of their Faith. Men's hearts are shown by the character of their works, and the fashion of their minds is betrayed by the nature of their actions. For there are some, as the Apostle says, “who profess that they know God, but deny Him by their deeds.” For the charge of denial is truly incurred when the good which is heard in the sound of the voice is not present in the conscience.
Indeed, the frailty of man's nature easily glides into faults: and because no sin is without its attractiveness, deceptive pleasure is quickly acquiesced in. But we should run for spiritual succour from the desires of the flesh: and the mind that has knowledge of its God should turn away from the evil suggestion of the enemy. Avail yourself of the long-suffering of God, and persist not in cherishing your sin, because its punishment is put off. The sinner must not feel secure of his impunity, because if he loses the time for repentance he will find no place for mercy, as the prophet says, “in death no one remembers you; and in the realms below who will confess to you?”
But let him who experiences the difficulty of self-amendment and restoration betake himself to the mercy of a befriending God, and ask that the chains of evil habit may be broken off by Him “who lifts up those that fall and raises all the crushed.” The prayer of one that confesses will not be in vain since the merciful God “will grant the desire of those that fear Him,” and will give what is asked, as He gave the Source from Which to ask. Through our Lend Jesus Christ, Who lives and reigns with the Father and the Holy Ghost for ever and ever. Amen.
