Our lives here on earth are full of trials and struggles (See Tests, Trials, and Turmoil). But we can have joy and happiness if we follow God's commandments. In Matthew 25 the Savior teaches us an important lesson about what we need to do. In the parable of the talents he tells us of three different servants (What's a talent?) . One is given five talents, one is given two, and one is given one. The first two men manage do double their money but the third hides his in the ground. The lord promises the first two men that they will be made rulers over many things but calls the last servant slothful and unfaithful. Why? He didn't lose any of his lord's money. It must be very important to Jesus Christ that we work hard and improve the great gifts that we have been given.
In our lives here on earth we need to do our very best. I testify that if we use our time and talents wisely our Lord will say of us, "Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord." (See Matthew 25:21)
