To me, The New Testament is a literal contradiction to The Old Testament.
Jesus and God in The Old Testament have literally nothing in common.
Jesus teaches love. God of The Old Testament literally just teaches war and killing.
Jesus loves children and says they should never be harmed.
God of The Old Testament sends two bears to kill 40 children.
How can anyone believe that these two are the same God is beyond me.
In fact, Jesus died exactly to abolish almost everything that god of The Old Testament did and promoted: Circumcision, Judgment, revenge, death for working on saturday, other types of death penalty used in The Old Testament, wars, God cherry-picking Israel while rejecting other nations.
So yeah, The Old Testament goes to shit.
Now, about The New Testament. The New Testament pretty much commands you to get yourself killed for Jesus and hate your life in order to enter heaven.
It also commands entirely unrealistic judgment towards homosexuals while at the same time tells us not to judge.
It also commands to marry, while at the same time says that 144,000 who entered heaven were all unmarried, while everyone else was killed and cast to hell.
Yeah, really gotta cherry pick what to follow and what not to follow.
I follow The New Testament, but only the parts that I cherry picked from it.
