Thanks for that! I can fairly relate. My grandmother and mother were the first converts and I grew up in the church. I attended primary, we had family home evenings and family prayer , and we were sealed in the temple. These things probably seem pretty elementary to most born in the church, but in the Philippines, these things (especially temple attendance) were pretty much a big deal. My father used to be a bishop... and then he left the church. And that was quite a blow to the family.
For several years, my family struggled through inactivity. I never finished seminary. I attended church whenever I was home due to my grandmother's insistence. (I went to high school in a neighboring province and I never set foot in a church there)
But when I went off to college in still a different province, I decided to seek my own testimony. I did share my testimony when I was younger but I always felt I was thriving on borrowed testimony. That time, I decided I had to find out for sure.
I looked for a ward near my school and I attended regularly. At first i was hesitant to attend institute, but I was amazed at how I can actually apply the principles taught to me. I kept attending church and at first I just attended merely to 'comply".. But little by little I was changing. I kept reading the Book of Mormon and though at first I was a skeptic, I found myself changing in so many ways... My friends said my countenance changed as days passed. I was given callings and at first though I was grudging of the time I'd lose out on my studies.. I began to enjoy it.... And eventually, I knew then that the church is true, and that Joseph Smith is a prophet, and that the Book of Mormon is true.
I am glad to have had a head start yet I am also grateful that I had the opportunity to find the church myself. Getting a testimony requires a bit of faith and a lot of effort - and then it's a feedback mechanism.. A bit of testimony gives you more faith and inspires you to give more effort..
