There is no better place than the Bible to go for comfort. As Pilgrim quoted from Psalms73:25,26 in the shout box, Christ is our greatest comfort.

Whom have I in heaven but thee? And there is none upon earth that I desire besides thee. My flesh and my heart faileth; But God is the strength of my heart and my portion for ever. Ps 73:25,26
Personally, I find great comfort from reading the Psalms, as so many of them touch upon many of the real struggles that people commonly face in life and provide godly wisdom in how we are to respond to them. You will find that all of the Bible gives completely trustworthy and reliable information about who God is and how man may come to know Him.

In the book of Job, we learn of a man who had to endure many great trials (including the foolishness of his friends). Job, as you know suffered incredible hardships and the best his friends could say, including his wife were wrong. Yet Job learned through this who his God was and could say by faith in Job 19:25 "For I know that my Redeemer lives." God put him through this time of testing and at the end of this time, Job was made firm in his faith and Job knew that he could trust God above all things, and in all things.

Al, I am sorry that you are having to endure so much sorrow and loneliness. It helps and is wonderful to hear of your love for your wife and how you care for her as you have been doing. It says much of about who you are and love for her. I am praying for you.

You do well to want to come to "the Book" as you said for it is the only place where you can learn true things of God. As you approach reading the Scriptures, pray that God will open the Scriptures to you that you may know more of God and of how He would have you to come to Him by faith in Christ. There are also many good articles here on The Highway that you might find helpful too. Ultimate Questions by John Blanchard is one of over 1,600 books, articles, and sermons that you will find. J.C. Ryle wrote a beautiful sermon on Prayer that is most comforting and instructive.

This is just a beginning Al and I hope of some use to you. Hopefully, others here will provide more help.
