The comfort I receive from my faith in God is that of an assurance that I have nothing to worry about. Our God, our Father sees all, and knows all, knowing the ending from the beginning, its already been taken care of. Romans 8:28 tells us that all things work together for the good and 1Peter tells us to cast all your care upon him;for he careth for you.
My personal relationship with God lets me know that He is true to his word. Numbers 23:19 states that God is not a man that he should lie nor the son of man that he should repent.
I can share this comfort by encouraging my friend or relative to trust in God as I have learned to do. Past experiences have proven to me that God is able.
Words of comfort I can bring to others would be based on my own experiences with God. The Bible tells us that faith cometh by hearing and hearing by the word of God.
