Be joyful always; pray continually; give thanks in all circumstances, for this is God’s will for you in Christ Jesus. (1 Thes 5:16-18)
Pray continually...without interruption. Give thanks in all circumstances (no matter what - good or bad) - why - because God wants us to!
It's easy to pray when things are going smoothly, or when we are happy. The challenge comes when the road is narrow and filled with pot holes.
We joke about the man in the car with his wife who will not ask for directions and is lost and late on the way to his destination. Isn't that all of us when it comes to prayer? We think we can "fix" or "figure out a solution" all by ourselves. How much easier it would be to pray! The answers will come; they do come! Only when we are on our knees, closer to God than we've ever imagined, can we fully experience all that he has for us! I know its hard - there are days that I just don't have it in me. There are days when I just want to exist alone and not reach out to God. Its only natural to want to turn to the logical solutions (and in some cases that is the answer). But we generally feel that when bad things are happening that God is punishing us ~ not so! He's asking us to reach out to him, so he can teach us something! If we draw closer to him in times of joy, how much easier it will be to draw closer to him in times of sorrow ~ praising him for ALL the things in our lives!
The man in the car eventually gets where he is going, and he's usually late and harried. I don't think I want to be "late" when it comes to the Lord! Being late in that instance may turn out to be "too late"! Be on time - now - pray without ceasing and rejoice in all that he gives you!
