Temples are literally houses of the Lord. In the temple we make sacred covenants, or promises, with God that are necessary for us to be with Him in the highest degree of heavenly glory (see D&C 131:1–4). These temple covenants lead to the great blessings available through Jesus Christ.
We are not expected to be perfect to enter the temple. Rather, the purpose of the things we learn and the covenants we make in the temple is to help perfect us. We must, however, be worthy to enter.
A temple recommend signifies that we have been found worthy through an interview with a member of our bishopric or our branch president and also an interview with a member of our stake presidency or mission presidency. Temple recommend interviews are opportunities for us to examine our worthiness. In each of the interviews, our priesthood leaders will ask us about our personal conduct and faith. Our priesthood leaders keep these interviews private and confidential.
If our priesthood leaders find that we are worthy to enter the temple, we will receive a temple recommend. We sign our recommend to confirm our worthiness to enter the temple. Our priesthood leaders also sign our recommend as additional witnesses of our worthiness. This recommend allows us to enter the temple for the next two years, provided we remain worthy.
The following are some of the topics your priesthood leaders will ask you about:
Your testimony of Heavenly Father, Jesus Christ, and the Holy Ghost.
Whether you sustain the President of the Church.
Whether you strive to attend church, keep the covenants you have made, and keep your life in harmony with the commandments of the gospel.
