Rollercoaster Ride

Why is it that sometimes we don't even have to try to have a great relationship with the Lord and other times we strive for that relationship but it just doesn't seem to be there, the feelings I mean? I have just had some of the best times with the Lord ever. Each week I would go to CIU on Tuesday mornings and each time something would stand out, maybe through prayer, reading the word, or even in a song. But now, even though I don't want it to happen, I feel some of that is fading. It's harder for some reason. I think that in these dry periods, that's when our perseverance is tested. I still want and need to hear from the Lord. I desire and long to hear his voice and feel His direction in my life. So now the question is, "Will I continue to seek God when I don't "feel" His presence? How about you?
