Can these bones live?

The prophet of God is called upon to preach to a valley of dry bones. God asks His preacher, if these bones can live. The wise steward answers by saying, Lord thou knowest. He did not presume upon God, nor did he doubt God. He simply placed it in the hands of God, and did as he was told. So must we all. Preach, as God directs, when He directs, and what he directs.
And maybe, just maybe...God will give life to those dead bones.
