John 8:7
7 So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
Should you really be the one to claim if another man is following Christ's example or not?
Nobody I've ever met is a perfect Christian especially myself. Joseph Smith was not a perfect Christian. He was just a man like the rest of us, doing the best he could. Sometimes he succeeded other times he failed. There has only been one person on the earth that was perfect and that was Jesus Christ. Everybody else, including prophets, are imperfect. Moses, Jonah, come to mind. Even Peter one of Christ's closest apostles denied him.
Rev 21:8(emphasis added)
8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
Should we condemn Peter because of His lies when he denied Christ?
When can you say that you've obeyed Christ's teachings 100%?
Matthew 7:5
Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye.
Perhaps you should work on bettering yourself as a Christian than casting stones at someone else.
