The first matter that the slave will be brought to account for on the Day of Judgment is the prayer. If it is sound, then the rest of his deeds will be sound. And if it is bad, then the rest of his deeds will be bad.
I like this thought: Your mind is a cupboard, and you stock the shelves. Let us make certain that our cupboard shelves, and those of our family members, are stocked with the things which will provide safety to our souls and enable us to return to our Father in Heaven. Such shelves could well be stocked with gospel scholarship, faith, prayer, love, service, obedience, example, and kindness
Prayer doesn't work because someone out there is listening, it works because someone in here is listening. I've paid attention. I've pictured what I want to happen in my life. I've meditated extensively on my family, my future, my past actions and what did and didn't work for me about them.
