A thought from the scriptures

 And now, because of the covenant which ye have made ye shall be called the children of Christ, his sons, and his daughters; for behold, this day he hath spiritually begotten you; for ye say that your hearts are changed through faith on his name; therefore, ye are born of him and have become his sons and his daughters. - Mosiah 5:7
 "When you choose to follow Christ, you choose to be changed," President Ezra Taft Benson counseled during the October 1985 general conference."Can human hearts be changed? Why of course! It happens every day in the great missionary work of the Church. It is one of the most widespread of Christ's modern miracles. If it hasn't happened to you - it should.
 "The Lord works from the inside out. The world works from the outside in. The world would take people out of the slums. Christ takes the slums out of people, and then they take themselves out of the slums. The world would mold men by changing their environment. Christ changes men, who then change their environment. The world would shape human behavior, but Christ can change human nature."
