Two friends recently told me they were jealous of my testimony of tithing & of the love of God. As we discussed why we had testimonies on different aspects of the Gospel, I realized most of us have different "strong" points in our testimonies. But we also have different "undeveloped" parts too.
I've contemplated my testimony and why I believe the things I go. I have a deep and strong testimony of the love of God, tithing, priesthood blessings, prayers, the scriptures, living prophets, and of my Savior. These all came by the combined experiences with life, personal study, and Deity.
For me, I realized my testimony is extremely undeveloped of chastity. I've had to seek God in repentance for breaking it's laws, but never developed the needed testimony to strengthen my conversion. Why is that? I believe it's because I have a testimony of living prophets and take the law of chastity as truth from them. But that can only sustain me for a short time. I need to gain a specific testimony of the law of chastity from God. Brigham Young taught:
The revelations of the Lord Jesus Christ, the spirit of truth will detect everything, and enable all who possess it to understand truth from error, light from darkness, the things of God from the things not of God. It is the only thing that will enable us to understand the Gospel of the Son of God, the will of God, and how we can be saved. Follow it, and it will lead to God, the Fountain of light, where the gate will be open, and the mind will be enlightened so that we shall see, know and understand things as they are (DBY, 34).
How do we know that prophets wrote the word of the Lord? By revelation. How do we know that Joseph Smith was called of God to establish his Kingdom upon the earth? By revelation. How do we know that the leaders of this people teach the truth? By revelation (DBY, 38).
How can you know the Latter-day work to be true? You can know it only by the spirit of revelation direct from heaven. What proved this work true to you … ? Was it not the spirit of revelation that rested upon you? … You should add to it day by day; you should add as the Lord gives—a little here and a little there, and treasure up truth in your faith and understanding, until you become perfect before the Lord and are prepared to receive the further things of the Kingdom of God (DBY, 36). (Teachings of Presidents of the Church: Brigham Young, (1997), 41–47)
My testimony of the love of God took months of personal study and seeking from God before that flame took and the fire grew. I'm expecting that same process as I start now to better develop the undeveloped parts of my testimony.
