There are many ways to exhort someone to pray. For example, we can testify that God has commanded us to pray always, or we can describe examples from scripture and from our own experience of the blessings that come from prayers of gratitude, supplication, and inquiry. For instance, I can testify that I know that Heavenly Father answers prayers. I have received direction and comfort from words that have come into my mind, and I know by the Spirit that the words were from God.(Eyring)
Receiving direction and comfort seem to be the two key benefits being said prayer can deliver.
However, I know of far more people who have made correct decisions and been comforted without prayer being involved at all.
So is it necessary and has it been necessary in your life?
