Through faith, we are kept by the power of God - 1 Peter 1:5
Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
The eternal security of a believer has two sides – a divine side and a human side. The divine side is that we are kept by the power of God, but it is through faith, which is the human side. This does not mean that we are saved only as long as we exercise faith. But we need to understand – where there is true faith, there will be a continuance, because saving faith always has the quality of permanence.
