Genesis

“A temple is literally the House of the Lord, reserved for ordinances of eternal significance. Those ordinances include baptisms, marriage, endowments, and sealings. Each temple is symbolic of our faith in God and an evidence of our faith in life after death. The temple is the object of every activity, every lesson, every progressive step in the Church. All of our efforts in proclaiming the gospel, perfecting the Saints, and redeeming the dead lead to the holy temple. Ordinances of the temple are absolutely crucial. We cannot return to God's glory without them.”
― Russell M. Nelson
