To this day I have had the help that comes from God, and so I stand here testifying both to small and great, saying nothing but what the prophets and Moses said would come to pass: that the Christ must suffer and that, by being the first to rise from the dead, he would proclaim light both to our people and to the Gentiles."
Acts 26:22-23

Note the following about Paul’s closing words:

Paul claimed no power or authority in and of himself, but gave all glory to God for having done what he had done.

That Paul claimed to have spoken of nothing but Christ and the gospel means that even in giving his testimony in court, Christ and the gospel were the main point.

Paul was careful to include not only Jesus’ death, but also His resurrection from the dead. This is essential, and sadly, often neglected. Giving our testimonies and even inviting people to church is not evangelism without Christ and the gospel. And Christ and the gospel must include the death and resurrection to be complete.

Lord, please fill our hearts and loosen our tongues to tell others about Christ and the gospel. And help us, Lord, not to leave out the most important aspects of the gospel: Jesus’ death and resurrection. Please save Your people as we proclaim Christ.
