Throughout Church History, theologians have discussed three levels of faith regarding Jesus Christ. In the Latin these three were recognized as “Noticia, Assentia, and Fiducia.” The first simply means to say yes I see or I notice something. I know that it is there. The second is to take that a step further and say not only do I notice it but I believe it’s true. The third step is not just noticing or assenting, but trusting or believing in it for my personal salvation. There are 
many discussions attempting to qualify what faith really is and how a person can be sure that they really do believe in Christ for their personal salvation.
In Acts 17:4, when Paul and Silas arrived in Thessalonica they taught from the “scriptures.” When the New Testament refers to the “scriptures” it means the Old Testament primarily. When they were finished presenting the evidence for Christ from the Old Testament scriptures, Luke writes, “And some of them were persuaded and joined Paul and Silas, as did a great many of the devout Greeks and not a few of the leading women.” Their faith, or act of believing, was referred to as a persuasion. Luke uses the same idea in Acts 19:26 when the makers of Diana idols in Ephesus were riled up against Paul’s preaching. That verse says, “And you see and hear that not only in Ephesus but in almost all of Asia this Paul has persuaded and turned away a great many people, saying that gods made with hands are not gods.” There are other passages as well where faith or believing is referred to as a “persuasion.” Agrippa heard from Paul at Caesarea and after Paul presented the case for Christ, In Acts 26:28 we read, “And Agrippa said to Paul, ‘In a short time would you persuade me to be a Christian?'”
Are you persuaded of the truth of Jesus Christ? The standard Creeds of Christendom in the past always seem to carry that idea. I believe in God! I’m persuaded that God exists. I believe in His Son, Jesus. I’m persuaded that Jesus is who He said He was. I believe in Christ’s death on the cross as paying the penalty for my sins. I’m persuaded that when Jesus said from the cross, “It is finished,” he really meant it and he meant it regarding me personally and my sins. As for me, I am persuaded.
