Paul's conviction

That's a bit suspicious of how many people at that time knew that they were Jesus Christ and God of Jesus without the experience of the resurrection. This is not a thing that can be so easily decided from the beginning that it was like this way. But at that time, in fact, wise men gathered to easily execute the Lord Jesus.
From here as well, it might be possible to understand roughly how people saw the Lord Jesus at that time. The faith in Christ the Son of God began in the hearts of the disciples who met the resurrected Lord Jesus and was strengthened by Pentecost.

So, for the past two years of the resurrection, the disciples would have seen what Jesus looked like. According to Paul's letter and the Acts, the center of the church's faith at that time was the resurrection of Christ. "The Jews ask for signs, the Greeks seek wisdom, but we say and tell the crucified Christ. This Christ stumbles upon the Jews and foolish ones for the Gentiles. There is, however, for the called oneself ... the power of God, the Christ of the wisdom of God (1 Corinthians 1-22-24) This sentence of Paul is strong that can not be defeated by anything It expresses faith, but at the same time it also shows that Christ actually looked stupid to Gentiles and stumped to Jews, or was Paul's writing just a contradiction as an ornament? Is it ironic to those who do not believe in Christ?

I don't think so. The cross may seem stupid to Gentiles and Jews, but is it ironic that there is no salvation other than the cross? It's not just a simple word. In fact, this is Paul's conviction itself. Paul was clear to anyone that the Lord Jesus was the Son of God, but everyone did not try to believe it. It never say that.
If Nazareth's Jesus had already been seen in the eyes of all as the Son of God's unbelievable God before the resurrection, Paul's way of saying might not have been a bit different either. Christ who believes in true oneself
It can not be written that "it was foolish and stumbling in the eyes of people."
