Elder Jeffrey Holland talks of Christ's gift to us ~ eternal life ~ so beautifully, "In His willing submission to death He took upon Himself the sins of the world, paying an infinite price for every sorrow and sickness, every heartache and unhappiness from Adam to the end of the world. In doing so He conquered both the grave physically and hell spiritually and set the human family free."
Because of Jesus Christ's sacrifice (his atonement) the gift of eternal life is available to you and me. Because of it, we are free to choose happiness and eternal life. Free agency is one of God's greatest gifts to us. Our Redeemer paid that "infinite price" so that we may also conquer physical and spiritual death someday, to enjoy a joyful eternal life with our loved ones. Through making good choices, which carry good consequences, and through repenting from the poor choices we make, our future is bright and hopeful indeed.
Here are a few scriptures about the hope of eternal life:
"And what is it that ye shall hope for? Behold I say unto you that ye shall have hope through the atonement of Christ and the power of his resurrection, to be raised unto life eternal, and this because of your faith in him according to the promise." [Moroni 7:41, The Book of Mormon]
"In hope of eternal life, which God, that cannot lie, promised before the world began . . . that being justified by his grace, we should be made heirs according to the hope of eternal life . . . that they which have believed in God might be careful to maintain good works." [Titus 1:2, 3:7-8, The New Testament]
Continuing cherished relationships. Many abilities can be restored to us in the eternities, as well as beloved relationships with people we cherish if we remain faithful. The "same sociality which exists among us here will exist among us there, only it will be coupled with eternal glory, which glory we do not now enjoy". To enjoy those eternal blessings we simply need to do our part and remain faithful to what God asks of us now (commandments) and repent when we've messed up (I like this definition of repentance).
The principle of compensation. Elder Joseph Wirthlin talked of the principle of compensation, "The Lord compensates the faithful for every loss. That which is taken away from those who love the Lord will be added unto them in His own way. While it may not come at the time we desire, the faithful will know that every tear today will eventually be returned a hundredfold with tears of rejoicing and gratitude".
I am so grateful for a wise Heavenly Father who loves us, His children, so much that he provided a plan for our eternal happiness.
