Peace be on you.
Sorry not true.
1-God reveals His message to people through Prophets [the most righteous person of time]
2-People follow him, some resist (free will), resistors are those who do not want to get lifted from raw state to high moral state of spirituality.
3-Eventually many people accepts Prophets message.
4-Then decline starts when more people fall to raw state of self [selfishness].
5-Prophet Moses (on whom be peace) came to uplift fallen human [slave] and gave them light of courage and victory based on spirituality though they resisted with him too].
6-They enjoyed success.
7-They declined and Moses's Messiah came for reform.
8-He was resisted, he was mocked as rebel, he was given sentence, the governor Pilate knew Jesus was innocent, he put him on cross on such time that he should not be there for long.
9-He was taken away from cross after some times, treated and migrated to meet other tribes of Israelite to deliver divine message.

10-Latter, Prophet Jesus (on whom be peace) was misinterpreted as literal Son of God and Unity of God was changed into Trinity which as subservient to Moses, Jesus had never thought.
11-Holy Quran and Holy Prophet Muhammad (peace and blessings of Allah be on him) were sent as promised in previos Books to complete the divine message, corrected this and reminded that God is One and Jesus (on whom be peace) was a human and Prophet to Bani Israel.
