Joseph Smith claimed to be the reclaimer of "the one true church" but his claims are patently and logically false. Don't fall for the claims of false teachers that bring in high-sounding antigospel nonsense.
For such men are false apostles, deceitful workmen, disguising themselves as apostles of Christ. And no wonder, for even Satan disguises himself as an angel of light. So it is no surprise if his servants, also, disguise themselves as servants of righteousness. Their end will correspond to their deeds. 2 Corinithians 11:13-15
The gospel is good news for anyone if they will humble themselves and repent and trust in the death, burial, and resurrection of Jesus Christ.
Have a great day!
