Although he was weak when he was nailed to the cross, he now lives by the power of God. We are weak, just as Christ was. But you will see that we will live by the power of God, just as Christ does.
A lot of people try to get rich from preaching God's message. But we are God's sincere messengers, and by the power of Christ we speak our message with God as our witness.
We don't do shameful things that must be kept secret. And we don't try to fool anyone or twist God's message around. God is our witness that we speak only the truth, so others will be sure that we can be trusted.
We had told him how much we thought of you, and you did not disappoint us. Just as we have always told you the truth, so everything we told him about you has also proved to be true.
Christ also brought you the truth, which is the good news about how you can be saved. You put your faith in Christ and were given the promised Holy Spirit to show that you belong to God.
God himself showed that his message was true by working all kinds of powerful miracles and wonders. He also gave his Holy Spirit to anyone he chose to.
