This paragraph from 31 Days of Praise was SO convicting to me! I should pray no matter how I feel—and perhaps especially when I'm not feeling like it!!
>>We get in trouble when we depend on our feelings in prayer. We start thinking we have to be in a praying mood to pray. Or we call our petitions "good prayers" if they give us a certain feeling. It's much better to just decide to pray, as God commands—regardless of how we feel. Charles Spurgeon wrote, "We should pray when we are in a praying mood, for it would be sinful to neglect so fair an opportunity. We should pray when we are not in a praying mood, because it would be dangerous to remain in so unhealthy a condition."<<
