Eternal Security is the doctrine that salvation cannot be lost because it is kept secure by Christ. Since it is not gained by anything we do, it cannot be lost by anything we do. Eternal Security does not mean that we can sin all we want (Rom. 6:1-2) because we have been freed from sin and are set apart for holy use (1 Thess. 4:7).

• John 10:27-28, “My sheep hear My voice, and I know them, and they follow Me; 28 and I give eternal life to them, and they shall never perish, and no one shall snatch them out of My hand.”
• 1 John 2:19,” They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, in order that it might be shown that they all are not of us.”
