These verses are focusing on what it really means to say "once saved, always saved". That little cliche that so many people use is not meant to tell the "professing believer" that they can live however they want to live , in sin and in wickedness after they have prayed the magical prayer. What it means to be "once saved, always saved" is that at the point of conversion, when a man recognizes his sin, and then realizes his need for a Savior to eliminate that sin, God imparts into that person a supernatural faith that causes that person to lean entirely on God and disregard everything else. That supernatural faith that is imparted because of the power of the gospel, reveals God's righteousness; and that imparted faith,because it is supernatural, a given gift by the grace of God, will last and persevere until the end.Why? because that faith is connected to the everlasting love of God, which nothing can separate the believer from.(Jer 31:3;Rom 8:35-39)So,because God has imparted a supernatural faith into the chosen believer, that faith will last and will endure because it originates from God. The believer may stumble, fall, mess up, and be tempted, but the believer, when they fall, cannot remain in a fallen state. They cannot remain in sin and in wickedness, because the faith within them will carry them and give them strength in their weakness.God willcome after His child with conviction,and chastening which will produce repentance. The true Christian cannot be comfortable in sin and comfprtable in a life of rebellion, they hate it. Because God started the work of supernatural persevering faith within the believer He will finish it and bring that believer into completion.( Philipians 1:6).
Once Saved Always Saved is not a lisence to sin...its not a magical 5 minute prayer and you can live how you want...its a supernatural faith that produces a hatred for sin, a faith that longs for God and holiness and righteousness until the end...no matter what it costs...
