Why can't a Buddha's power just save us already? Like Jesus

I am a faithful believer in the Buddha's teachings and I even believe in the iddhi powers they all had and that show up in our day as well. I also believe in the various Bodhisattvas and Buddha's even within Taoism and contemplate and marvel at them every day, their mysteriousness, hard work and wisdom. Some of the scriptures have some astounding excerpts though of millions of bodhisattvas and deities... Which is why I wonder why, if we are: 1. a bundle of skandhas with no central core; 2. quite subject to cause and effect; 3. crying for saving; 4. individuals the omnisicient, omnipresent, omnipotent (iddhis ) buddhas and bodhisattvas have vowed to save from actual suffering and also awaken; Then why don't the billions of bodhisattvas and buddhas just make manifestation bodies and march across the universe and pacify and awaken everything as the first Buddha vow states? What is your opinion on this matter?
