If satan could ‘grab’ any Born from Above Christian then satan would be more powerful than God. Think, for the sake of your immortal soul, THINK! Salvation is ONLY in God’s hands. Once you profess anything even close to what Peter professed in Matthew 16:16, GOD’S Spirit takes over and you are hide in Christ. The degree to which you grow in His Grace and His Knowledge depends then upon how much you turn yourself over to His transforming you. But that is not about Salvation it is about what shows up at the Bema Seat in Heaven. IF once saved you7 could be unsaved your salcation guarantee would be based on your abilities, and the response to such blasphemy is God Forbid. If you have to earn ANYTHING in the Salvation calculation then it is no longer by Grace ... THINK!
One is not saved by believing one is saved by grace. One must obey the Messiah and keep his commandments. Watch therefore: for ye know not what hour your Lord doth come. But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up. Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh. Who then is a faithful and wise servant, whom his lord hath made ruler over his household, to give them meat in due season? Blessed is that servant, whom his lord when he cometh shall find so doing. Verily I say unto you, That he shall make him ruler over all his goods. But and if that evil servant shall say in his heart, My lord delayeth his coming; And shall begin to smite his fellowservants, and to eat and drink with the drunken; The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of, And shall cut him asunder, and appoint him his portion with the hypocrites: there shall be weeping and gnashing of teeth. Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.
