Strengthen the Spirit

The achieving of the true purpose of mortality requires a cooperation between the spirit and the body. The spirit is the disciplinarian; therefore, the spirit needs to be the stronger of the two. If the spirit becomes weak, the urges of the senses take over and sin or violation results. The weak spirit, however, can become strong through a process called worship, or adhering to all the principles as set forth in the gospel. The stronger the spirit becomes, the better the discipline of the body. As the spirit becomes strong, it prepares the soul to maintain, or keep, the second estate so that it may receive its right place in immortality.
