How do you believe in Jesus when you don't accept the other parts of the Bible as factual? ... No one can obey all the commandments. All have sinned and have fallen short of the glory of God.
Shalom, Aibrean.
Why I believe in The Tanach: Elohim proved He is master over all things (time & space) based on fulfilled prophecy all throughout the Tanach. Messiah fulfilled prophecy from the Tanach and His prophecies have also come true, grounding my faith
in the Gospels. The test of an authentic message from Elohim is not mainly the authority of or the identity of the person who communicated it, but the message itself (Deu 13, Deu 17:6, 19:15, Mt 18:16). The message must be consistent with prior revelation (Isa 8:20), they must point people to YHVH Elohim's Torah and Testimony (Isa 8:19,20), and all prophecies must come to pass (Deu 18:22, Jer 28:9), among other tests. The
epistles of James, Jude, John, and the Revelation also passes those tests, to my knowledge, so I believe in those. I believe Paul fails those tests as I've documented in
another thread.
How can anyone claim to believe in Elohim and Messiah, but do not obey His commandments (John 14:15)? Messiah warns that many will come in His name (Mat 24:5), and false prophets will rise (Mat 24:11) to deceive them, showing great signs and wonders to deceive the elect (Mat 24:24). Paul claims that signs and wonders performed at his hand are evidence that he is an apostle (2Cor 12:12). Messiah warned us of the opposite, that
false prophets will show great signs and wonders to deceive the elect (Mat 24:24)!
Messiah warns us to be careful that nobody deceives us (Mat 24:4). We can obey Messiah by obeying Elohim's commandment to test all "prophets" - including Paul, since he claimed to speak for Messiah and Elohim. Are we being careful if we close our eyes and accept everything by blind faith? I am not willing to risk my eternal salvation by doing that and by ignoring those commandments.
BTW, I do not obey the commandments necessarily for salvation, but for sanctification. I know I cannot obey all the commandments, but I know Elohim knows
my heart wants to obey all I can. Sin is not just a vague idea of "doing wrong" ... John explicitly defined what sin is: transgression (breaking or abandoning) the Law (1 John 3:4).
