Kerim, you will have to show according to the words of Jesus,
taken in their plain meaning of the Greek,
that he is of the form of "Christianity" which according to you, no one other than you holds.
Jesus' teachings are about salvation from the condemnation of God's wrath (Jn 3:18, 36) on one's guilt of sin.
Jesus' teachings are that it is only those who believe and trust in who he says he is:
the Son of God from heaven (Jn 3:13, 6:38, 42, 62)
sent by God (Jn 5:36-40, 10:36, 13:3, 16:28)
to die as a ransom (pay the price) for the sins of many (Mt 20:28, 26:28; Jn 10:11),
with power to forgive sin (Mt 9:2-6),
to speak for God (Jn 7:16, 8:25-28, 12:44-45, 49-50, 14:10; Lk 9:35, 10:16),
to judge all mankind (Jn 5:22, 27, 8:26, 12:48; Mt 25:31-33),
as the exclusive way to God (Jn 14:6),
the source of all truth and life (Jn 1:4, 5:25-26, 6:39-40),
the decisive factor in the eternal destiny of every man (Jn 3;18-19, 36, 5:24, 6:40, 8:24-25), and
possessing all authority (power) in heaven and earth (Mt 26:64, 28:18; Lk 10:22; Jn 13:3, 13),
who will die with their sin forgiven (Jn 8:24-26)
and saved from God's condemnation on their guilt of sin at the final judgment (Jn 3:18, 36).
So, according to Jesus, these are the things which you must believe and trust in (Mk 1:15).
Apart from believing and trusting in these things, one is not following Jesus' teachings.
Jesus came, not just to reveal God's truth, but most importantly to die
as a ransom from God's justice on the guilt of those who love, believe, trust and
obey him, and which ransom is applied only by saving faith (Jn 3:16, 18).
This is the Christianity spoken by Jesus, to which all those who are born again subscribe.
If one does not subscribe to all of them, Jesus says he is subject to God's condemnation (Jn 8:24-26).
It is not my intention to make you believe the Christianity spoken by Jesus.
My intention is only to show what Jesus himself states that his Christianity is.
