"Whatever your hand finds to do" refers to works that are actually possible. There are many things our heart finds to do that we will never accomplish. It's well that they are in our heart—but if we would be eminently useful, we must not be content with forming schemes in our heart and talking about them. We must practically carry out whatever our hand finds to do.
One good deed is worth more than a thousand brilliant theories.
Do not wait for large opportunities or for a different kind of work. Do just the things you find to do day by day. We have no other time in which to live. The past is gone; the future has not arrived; we never shall have any time but time present. Then do not wait until your experience has ripened into maturity before you attempt to serve God. Endeavor now to bring forth fruit. Serve God now!
But be careful how you perform what you find to do—"do it with your might." Do it promptly! Do not fritter away your life thinking of what you intend to do tomorrow as if that could compensate for the idleness of today. No man ever served God by doing things tomorrow. If we honor Christ and are blessed, it is by the things we do today.
Whatever you do for Christ, throw your whole soul into it. Do not give Christ a little slurred labor, done as a matter of course now and then. When you serve him, do it with heart, and soul, and strength.
But where is the might of a Christian? It is not in himself, for he is perfect weakness. His might lies in the Lord of Hosts. Then let us seek his help; let us proceed with prayer and faith, and when we have done what our hand finds to do, let us wait upon the Lord for his blessing.
What we do thus will be well done, and will not fail in its effect.
Closing Prayer
What task has God put right in front of you today? Stop planning. Stop waiting. Do it now, with all your might, in his strength.
