"Since ye seek a proof of Christ speaking in me, which to you-ward is not weak, but is mighty in you.
For though he was crucified through weakness, yet he liveth by the power of God. For we also are weak in him, but we shall live with him by the power of God toward you.
Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?"
2 Corinthians 13:3-5
Interesting verses. We often seek "proof" of God. A sign... something overpowering that would show us for certain that God is who he says he is. For God to talk back to us and show us that he is there. And then something happens in our lives that seems miraculous, or we feel the spirit strongly, and know in that moment that all of it is true... but then after, we again doubt, or explain it away, and start seeking more proof.
Paul, here, asks us to examine ourselves to find that proof that we keep seeking. Christ could be crucified because he had a weak, mortal body... but he rose, and lives now, because of a greater power. And the same is true in us, albeit to a lesser extent. Our bodies are weak, and we know our limitations. And yet, we are able to go beyond them because of a greater power than our own. If we look back on our lives can any of us say that we made it through alone? There are times in all of our lives when we've drawn on the power of God in order to make the effort, overcome the challenge, accomplish the thing, or pull ourselves out of the mess that we made of our own lives. Unless we're reprobates (probably meaning people who would lie to themselves and others about it, or refuse to feel or understand it), we can't look at our own lives and see no evidence of God.
Today, let's work on not being reprobates. :) Let's examine our own lives and see the evidence of God. And when we do, let's write it down, so that in the future when we doubt, we can look back and remember our own testimony of feeling and knowing the truth of God in our lives.
