Be diligent to present yourself approved to God as a workman who does not need to be ashamed, handling accurately the Word of Truth (2 Timothy 2:15).
The doctrine of the perseverance of the saints is to the effect that they whom God has regenerated and effectually called to a state of grace, can neither totally nor finally fall away from that state, but shall certainly persevere therein to the end and be eternally saved. – Berkoff
Our perseverance is dependent upon God. Man’s eternal redemption is because of God’s perseverance. Out of a lack of understanding, some object to this doctrine. One such objection is that the doctrine of perseverance leads to indolence and immorality. It is simplistically interpreted by some as, “Oh yeah, once saved always saved. I can get saved and live like the devil.” Berkoff answers this objection:
It is confidently asserted that the doctrine of perseverance leads to indolence, license, and even immorality. A false security is said to result from it. This is a mistaken notion, however, for, although the Bible tells us that we are kept by the grace of God, it does not encourage the idea that God keeps us without constant watchfulness, diligence, and prayer on our part. It is hard to see how a doctrine, which assures the believer of perseverance in holiness, can be an incentive for sin. It would seem that the certainty of success in the active striving for sanctification would be the best possible stimulus to ever-greater exertion.
