Sometimes, by the time we decide we need to go to God is prayer, out lives have gotten pretty down trodden. We have done a pretty good job of messing things up and making bad decisions all by ourselves. This verse in 1 Chronicles reminds us to seek His face ALWAYS. Look to Lord AND his strength, not simply FOR his strength. We aren't supposed to wait until we feel weak and weary and then call out His name. If we would go to him for everything and always, it would become a habit, it would become easy and maybe we wouldn't FEEL so abandoned. I emphasize the word feel because that is all it is, a feeling, not a reality. God has not abandoned you, but maybe, just maybe you have abandoned him on occasion.
So today and every day, look to the Lord and His strength, seek His face ALWAYS, not just when you are in need and remember everything He has helped you through and to accomplish. Coming to God is like working a new muscle. It is hard at first to do it every time you need to but as you get stronger, you realize you don't want to quit. You don't just do it because you are weak and need, now you do it to stay strong. We don't just come to God in times of need and weakness, we need to come to Him for everything. We need to praise Him for everything, we need to look to Him for our strength continually.
