One of my favorite scriptures is found in the 7th chapter of the gospel of Matthew. "Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven." This verse shows us that faith is a pre-requisuite for eternal life in our Heveanly Father's kingdom. We must know that Christ is our Savior, and we must rely on him for salvation. However, faith alone will not get us into heaven.
Faith is a principle of action. Those who have received the witness that Jesus Christ is their Savior must be willing to then DO the things that He and His Father have asked of us. Let us all "awake" and do those things today. Let us not forget the witnesses we have recieved, and use those to motivate us to come closer to God every single day.
Alma 32:34: "For behold, this life is the time for men to prepare to meet God; yea, behold the day of this life is the day for men to perform their labors."
