James 4:14-17

Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away. For that ye ought to say, If the Lord will, we shall live, and do this, or that. But now ye rejoice in your boastings: all such rejoicing is evil. Therefore to him that knoweth to do good, and doeth it not, to him it is sin.

Since we never know what is going to happen tomorrow we need to prepare ourselves today to meet God. As we learn about Christ and his teachings we need to start following them. To know about the teachings, and not follow them will only lead to our heartache. As we learn about Christ’s teachings we need to start following them today, not tomorrow.
