30 There are also many other signs (attesting miracles) that Jesus performed in the presence of the disciples, which are not written in this book; 31 but these have been written so that you may believe [with a deep, abiding trust] that Jesus is the Christ (the Messiah, the Anointed), the Son of God; and that by believing [and trusting in and relying on Him] you may have life in His name. [Ps 2:7, 12]
