Elder Renlund gave a great distinction between the gospel of Jesus Christ and The Church of Jesus Christ, teaching -
"...the combination of the gospel of Jesus Christ and The Church of Jesus Christ of Latter-day Saints provides powerful and transformative benefits for us. The gospel is perfect, but a divinely commissioned church is required to preach it, maintain its purity, and administer its sacred ordinances with the Savior’s power and authority.
Consider the combination of the Savior’s gospel and His Church as established by the Book of Mormon prophet Alma. The Church was responsible for preaching “nothing save it were repentance and faith on the Lord, who [would redeem] his people.” Using God’s authority, the Church was responsible for administering the ordinance of baptism “in the name of the Lord, as a witness [of entering] into a covenant with him [to] serve him and keep his commandments.” The people who were baptized took on themselves the name of Jesus Christ, joined His Church, and were promised great power through an outpouring of the Spirit."
"The Church is simply ordinary people, disciples of Jesus Christ, gathered and organized into a divinely appointed structure that helps the Lord accomplish His purposes. The Church is the instrument through which we learn the central role of Jesus Christ in Heavenly Father’s plan. The Church offers the authoritative way for individuals to participate in ordinances and make lasting covenants with God. Keeping those covenants draws us closer to God, gives us access to His power, and transforms us into who He intends us to become."
'The Church of Jesus Christ of Latter-day Saints enables access to God’s power because it is authorized by Him both to teach the doctrine of Christ and to offer the gospel’s saving and exalting ordinances. The Savior yearns to forgive our sins, help us access His power, and transform us. He suffered for our sins and longs to pardon us from the punishment that we otherwise would deserve. He wants us to become holy and be perfected in Him.
Jesus Christ has the power to do this. He didn’t simply sympathize with our imperfections and lament our eternal condemnation in consequence of sin. No, He went beyond that, infinitely beyond that, and restored His Church to enable access to His power."
