My testimony that this is the true Church began in my childhood. One of my earliest memories is of a conference meeting. A man was speaking whom I did not know. I knew only that he was someone sent to our little district in the mission field by someone who held the priesthood. I do not know what he said. But I received a powerful, certain witness before I was eight, even before I was baptized, that I was hearing a servant of God in the true Church of Jesus Christ.
In my teen years, I felt the power of priesthood quorums and of a loving bishop. I still remember and can feel the assurances that came when I sat in a priests quorum next to a bishop and knew that he had the keys of a true judge in Israel.
That same witness came early in my life on two Sundays. In each case I was present on the day that a stake was organized. Seemingly ordinary men whom I knew well were called as stake presidents. I raised my hand on those days and had a witness come to me that God had called His servants and that I would be blessed by their service and for sustaining them. I have felt that same miracle countless times across the Church.
I saw that those stake presidents were lifted up to their callings. I have seen the same miracle in the service of President Monson as he received the call to preside as the prophet and President of the Church and to exercise all the keys of the priesthood in the earth. Revelation and inspiration have come to him in my presence, which confirms to me that God is honoring those keys. I am an eyewitness.
I bear you my solemn witness that this is the true and living Church of Jesus Christ. Heavenly Father will answer your fervent prayers to know that for yourself.
