What is your faith and what is Jesus's faith?
One can get caught in semantics. The faith that dwells in us is very real.
I live by faith in the Son of God
Gal 2:20
Faith in Christ, the revelation He is the Messiah, the Christ, is a gift from God.
But it is our faith, that keeps us in Christ.
Your description could easily be interpreted that if we fall away it is Gods fault, and He alone has responsibility to keep us in Him.
Peter when told he would deny Jesus, Jesus told him when he came back to encourage the brothers.
31 "Simon, Simon, Satan has asked to sift you as wheat.
32 But I have prayed for you, Simon, that your faith may not fail. And when you have turned back, strengthen your brothers."
Luke 22:31-32
We are in a free will relationship with Jesus and He calls us onward, Amen.
His faith, and our faith, to me, the lines get blurry.
It's like in Romans 8 . . .
15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16 The Spirit itself beareth witness with our spirit, that we are the children of God:
The Spirit, by which we cry . . . my spirit and God's spirit bearing witness together, we are His children. Where does His Spirit end and mine begin? I find I can't tell.
I think it's the same with faith. God has given to each a measure of faith. We mix that faith with His Word, and live. We believe, with the faith from Him.
31 "Simon, Simon, Satan has asked to sift you (Plural 'you') as wheat.
32 But I have prayed for you, Simon, that your (singular 'your') faith may not fail. And when you have turned back, strengthen your brothers."
Luke 22:31-32
Jesus warns Simon that Satan has asked to sift as wheat all the disciples. Jesus assures Simon that He has prayed that Simon's faith not fail. And in faith that this will be so, His prayer answered, Jesus tells Simon, when you've returned, strengthen the others.
Peter couldn't stand the idea, I think, of following Jesus to crucifixion, at least, not yet. But even the misery of denying his Lord out of whatever state he was in that would bring him to do that, Peter did not stop believing in Jesus, at least, not so far as I can tell.
Jesus prayed that Peter's faith not fail, and Peter went the distance.
1 John 2
18 Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.
19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
One among us, unknown, until they go out. These didn't go the distance. Because they were never true.
Hebrews 3:14 "For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end;"
This is about going the distance. IF we hold our faith to the end. If we do, we are 'made partakers' of Christ, which is a perfect tense, showing something that was done, and remains done. Like a bell. You cast a bell, hang it with a clapper, but no one has rang it yet. You walk over, swing the clapper, Bing! Now this is a "rung bell". It will always be a rung bell, it never goes back to being "unrung".
Paul uses the same tense when he says, Have I not seen the risen Christ? He is one who has seen the risen Christ, and forever that remains true.
IF we hold our confidence to the end, we have become partakers of Christ, in this same way. It was done, remains done, we will evermore be partakers of Christ. If it's real, it lasts.
I don't hold God responsible for the one who professes faith one day, and another day professes something else.
Much love!
