OldRegular,
You quoted of passages on security salvation.
John 6:35-40: many baptists saying, when anyone who come to Christ, Christ will not cast saved person out, and Christ will not lose anyone. This passage prove of security salvation.
I want to show you verse 35 and 37; Christ said: "he that cometh to me "cometh" in present tense means coming. This is speak of individual's decision and freewill want to come to Christ for salvation same in Rev. 22:17 says, "And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will let him take the water of lifee freely." This verse tells us, we allow anyone who desire want to be saved, let person come in freewill decision.
Same otherwise, Christ says, "come and follow me". So, in word, 'cometh' is a present tense means continue follow him in present tense, therefore, Christ will not cast person away, while follow him same time. Or, if anyone do not want to come to Christ, then person would not be saved. In other word, if person stopped follow Christ, then Christ would cast person away same as John 15:6; and Romans 11:19-23.
Back to John 6:35. Notice Christ said, "...and he that believeth on me". 'Believeth' is a present tense means currently believe or believing. Anyone who believing in Christ, will not cast away. If anyone is stopped believing, shall be cast away according Romans 11:19,20.
Also, in John 6:37, Christ said, "him that cometh to me". 'Cometh' is a present tense, means currently come well as same as 'coming'. 'Coming' is same common sense as "follow Christ". Christ promises us, if anyone is continue following him, so He will not removed person away while following Him. Or, if a perosn stopped follow him, person would be removed away.
John 6:35-39 telling us, that the promise to us as individual, if anyone who is continue follow Christ, therefore, will not cast away.
John 10:27-30 Many baptists or securists citied this passage as security salvation proof. They saying that no one can take us away from Christ's hand. Because Christ have the power to hold us-salvation. That's true. Amen!
But, look at John 10:27 says, "My sheep HEAR my voice, and I know them, and they FOLLOW me:"
There are two key words in this verse- 'hear' and 'follow'. Both are present words. Christ promises us, if anyone hear the gospel, and then to follow Christ, no one will take us away out of his hand, long as are still secure in his hand-salvation. OR, otherwise, if we stopped listening, and follow Him, then He would loose us out of his hand. Both 'hear' and 'follow' are conditional, that we are responsible to meet for our salvation. We must continue follow Christ all the way throughout our life till die, or Christ comes. Or, if we quit follow Christ in the midst of our life, and fall back to world, when by the time we die, then we will not be saved - Matt. 10:22; & Matt. 24:13. Matt. 24:13 commands us that we ought to endure all the way till death or Lord comes, do not quit. If we quit, then we shall not have eternal life at the end.
Romans 8:28-30 Many securists citied this passage as security salvation proof. But, the context of Romans 8:35-39 nothing say anything about salvation. This context talking about God's LOVE. Everything cannot separate us(faithful Christians) from God's Love. No matter what situations, we facing, God still love us always all the times.
In Christ
Rev. 22:20 -Amen!
