Reasonable, logical, believable

Come let us reason together so you understand what we believe.

"Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil;Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow. Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool. If ye be willing and obedient, ye shall eat the good of the land: But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the Lord hath spoken it" (Isaiah 1:16-20).

There is a god.

There a plan.

God communicates through prophets now as he did before.

God the Father and Jesus Christ are separate beings in whose image we are created. The Son prayed to the Father and the Father bore witness of the Son. John 8:13

Jesus Christ was the Son of God as He claimed.

Christ organized a church that He intended should administer the ordinances of salvation.
Ephesians 4:11-16

Eventually the Church He established fell into apostasy as was prophesied. Isaiah chapters 29,30. The Protestant reformers also said that the church doctrine had changed and the authority was lost.

The Book of Mormon is a true testimony of Jesus Christ translated from ancient records by a young, uneducated farm boy in a singled draft.

Joseph Smith really did see the Father and the Son. He re-introduced to the world many doctrines and organizational structures that were unknown in his day. The church he founded is called "The Church of Jesus Christ of Latter-day Saints" because Christ is the head, and the prophets and apostles He calls to lead it are guided by Christ.

All this is reasonable, logical, and believable, but my testimony is based on a confirmation by the Spirit. The more sure testimony of the Holy Ghost is more powerful than reason.
"Behold, I say unto you they are made known unto me by the Holy Spirit of God. Behold, I have fasted and prayed many days that I might know these things of myself. And now I do know of myself that they are true; for the Lord God hath made them manifest unto me by his Holy Spirit; and this is the spirit of revelation which is in me" (Alma 5:46)
