'Siding' in the Bible

Immediately they left their nets and followed Him [becoming His disciples, believing and trusting in Him and following His example].

Jesus called the crowd together with His disciples, and said to them, “If anyone wishes to follow Me [as My disciple], he must deny himself [set aside selfish interests], and take up his cross [expressing a willingness to endure whatever may come] and follow Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me].

Peter started saying to Him, “Look, we have given up everything and followed You [becoming Your disciples and accepting You as Teacher and Lord].”

And he left everything behind and got up and began to follow Jesus [as His disciple].

He who is not with Me [believing in Me as Lord and Savior] is against Me [there is no impartial position]; and he who does not gather with Me [assisting in My ministry], scatters.

But the people of the city were divided, some siding with the Jews and some with the apostles.

whose fate is destruction, whose god is their belly [their worldly appetite, their sensuality, their vanity], and whose glory is in their shame—who focus their mind on earthly and temporal things.
