Personal worthiness 1

D&C 95:8 The Lord declares that He commanded that a temple is built so He could endow those whom he has chosen "with power from on high".
Mosiah 26: 29 preaches repentance.
It is a condition to be personal worthy to be able to enter the House of the Lord or the temple. A missionary holds a title of more power when he/she is endowed in the temple. This principle of being endowed then entitled to more power partakes of the blessings from Heavenly Father because He trusteth the one he has chosen.
We must repent sincerly and properly prior to enter the temple. Consequently, it also means we must repent sincerly and properly prior to enter the mission field. We must believe in repentance, so we will be able to preach to others with a peace of conscience. We must rise up from our sins and come unto Jesus-Christ with a sincere heart, so He will not remember our sins no more. It is strongly encouraged to be true and honest about our personal worthiness before entering the mission field because again it is a great and marvelous work.
