John 4:48 So Jesus said to him, “Unless you see signs and wonders you will not believe.”

Believe (pisteuo) means to have confidence in, to affirm, or to entrust.

Will you believe by taking Jesus at his word, or do you require signs and wonders?

Believing in Jesus’ word is believing in Jesus himself.
The evidence of our belief is the way we respond.

John 20:30-31
