God uses your faith to mold your character. Character is the manifestation of what you are becoming. Strong moral character results from consistent correct choices in the trials and testing of life. Your faith can guide you to those correct choices. Clearly, it is what you do and what you think about that determine what you are and what you will become. Therefore, the choices you make need to be inspired by the Lord. Others can encourage you to make the right decisions, but those choices must not be prescribed by them. You need to ponder, pray, and exercise faith to willingly make choices consistent with the teachings of the Master. Such choices are made with trust in things that are believed and when acted upon will be confirmed. Only enough guidance is given to lead you aright and not to weaken your growing character. That guidance will solidify your trust in Heavenly Father and the Savior.
Faith will forge strength of character available to you in times of urgent need. Such character is not developed in moments of great challenge or temptation. That is when it is used. Character is woven patiently from threads of principle, doctrine, and obedience. In James we read: “The trying of your faith worketh patience. But let patience have her perfect work, that ye may be perfect and entire, wanting nothing.” The bedrock of character is integrity. Worthy character will strengthen your capacity to obediently respond to the direction of the Spirit. Righteous character is what you are becoming. It is more important than what you own, what you have learned, or what goals you have accomplished. It allows you to be trusted. Righteous character provides the foundation of spiritual strength. It enables you in times of trial and testing to make difficult, extremely important decisions correctly even when they seem overpowering. I testify that neither Satan nor any other power can weaken or destroy your growing character. Only you could do that through disobedience.
