Rather,
1 Peter 1:3-5 KJV
3) Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,
4) To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
5) Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
The saying here is that the power of God keeps us, using faith as the means.
"kept" here is a Perfect tense verb, meaning it's an action that is completed with enduring result. It's done, and remains done. It's in the Passive Voice, which means it's being done to the one who is being kept. I receive His "keeping" of me. If I were "keeping myself", say, by, for instance, fulfilling a requirement to continue to believe, then it would be written in the Active Voice, which means I'm doing the action.
A parallel passage is here,
Ephesians 4:30 KJV
And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
Here, "Ye are sealed" is Passive Voice, done to us. The Holy Spirit is our seal of being owned by God, His property, and we are under His seal "unto the day of redemption". Can you extricate yourself from God's ownership of you? Are you able to do that? Because He's said it's not going to happen. That if you're raised with Him now, you will appear with Him then. That His seal of ownership has an intent, that I be locked up under His seal until that day.
Much love!
