'Believing' in the Bible

because on account of him many of the Jews were going away [from the teaching and traditions of the Jewish leaders] and believing in Jesus [following Him as Savior and Messiah].

But Jesus loudly declared, “The one who believes and trusts in Me does not believe [only] in Me but [also believes] in Him who sent Me.

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.
