There are many religions but logically the truth can only be one. You can’t have multiple truths be real all at once. So the idea that God aproves all religions is absurd. For example some religions teach that there is life after death in heaven or hell, or some others teach that there is reincarnation. Obviously both can’t possibly be true. So you’re gonna have to look at what the Bible says. In (Revelations 21:4) teaches us that there will be resurrection and no more pain or death. So which religion is the best religion? I say the best religion is the one that abstains from false and pagan traditions like Christmas and Easter which have no biblical standpoint and follow what the Bible strictly mentions.
