As I look back over my life, there have been a multitude of "moments.” I think that being a friend of God is trusting HIM in each and every one of those "moments." Basically, it's keeping God at the forefront of your mind in every situation that comes across your path. God is faithful.
When you're happy, in difficulty, in quietness and in pain, you can be assured that at EVERY moment he is with you. Meditate on that and it should bring you nothing but THANKS knowing that you are in safe hands.
