There might be moments in your life when this seems impossible. Since God has put you through this trial, why then should you rejoice in the Lord?
Life is a vaccumm, oh how hard it is to pull away from its grasp. This is when you need to praise the Lord the most! This is the moment when you can transcend to a life of sin and bitterness or stand up to the trial. You have a choice to make, descend into the easy path of darkness or walk up the steep hill to the light. The second evil thoughts enter your mind is when you should shout out a song, cry out a verse. Let the World know that nothing can snuff out your candle!
The more you worship Him, the less you focus on your trials. The less attention we pay to our trial, the more tranquility and ease we find in our lives. Making every day easier and easier as the trial delves on.
So when it seems the hardest to press on, praise the Lord.
