From the Deseret News report:
“The First Presidency and Quorum of the Twelve Apostles counsel together and share all the Lord has directed us to understand and to feel, individually and collectively,” he said. “And then, we watch the Lord move upon the President of the Church to proclaim the Lord’s will.”
This “prophetic process” — which also includes fasting, prayer, studying, pondering, counseling with each other as they wrestle with the issue — was followed in 2012 with the change in age for missionary service, as well as the recent additions to the Church’s handbook, consequent to the legalization of same-sex marriage in some countries, President Nelson said.
“Filled with compassion for all, and especially for the children, we wrestled at length to understand the Lord’s will in this matter,” he said. “Ever mindful of God’s plan of salvation and of His hope for eternal life for each of His children, we considered countless permutations and combinations of possible scenarios that could arise. We met repeatedly in the temple in fasting and prayer and sought further direction and inspiration.
“And then, when the Lord inspired His prophet, President Thomas S. Monson, to declare the mind of the Lord and the will of the Lord, each of us during that sacred moment felt a spiritual confirmation. It was our privilege as Apostles to sustain what had been revealed to President Monson. Revelation from the Lord to His servants is a sacred process. And so is your privilege of receiving personal revelation.”
