Don't concentrate on what you lack, concentrate on what you have. Then give all of it to Jesus for His use.
One of the most effective ways to pray is to ask God to give you a promise from his Word concerning whatever it is you're praying for. Then hold him to his Word as you pray it back to him. It's what has been called "reversed thunder." God keeps his Word, and basing our prayer on his Word gives our prayers strength and confidence because we know we're asking for something God wants to give us.
The organized church sometimes puts boundaries on us that the Bible doesn't. So I'm living my life for an audience of one. I live my life to please God. Some people won't understand, but I don't give an account to some people.
Suffering may be someones fault or it may not be anyones fault. But if given to God, our suffering becomes an opportunity to experience the power of God at work in our lives and to give glory to Him.
For myself I never plan the way I deliver a message. I do prepare the content, and then I open my mouth and give it. And so the expression, the gestures, the emphasis on words, all of that just comes.
