Alma 5:26

"And now behold, I say unto you, my brethren, if ye have experienced a change of heart, and if ye have felt to sing the song of redeeming love, I would ask, can ye feel so now?"

I love Alma chapter 5. It is full of questions to ask yourself and see how you are doing before the Lord.  I especially like this verse because it helps me evaluate my life and see if I am still feeling the Spirit in my life.  Past spiritual experiences are nice but they should not stop.  Testimonies must be continually cultivated in order for them to last.
