The first principle of the gospel is faith in the Lord Jesus Christ. Having faith in Christ includes having a firm belief that He is the Only Begotten Son of God and the Savior and Redeemer of the world. We recognize that we can return to live with our Heavenly Father only by relying on His Son’s grace and mercy. When we have faith in Christ, we accept and apply His Atonement and His teachings. We trust Him and what He says. We know that He has the power to keep His promises. Heavenly Father blesses those who have faith to obey His Son.
Faith in Christ leads to action. It leads to sincere and lasting repentance. Having faith causes us to try as hard as we can to learn about and become more like our Savior. We want to learn what His commandments are and then obey them. Even though we will still make mistakes, we show our love for Him by striving to keep His commandments and avoid sin.
We believe in Christ, and we believe that He wants us to keep all His commandments. We want to show our faith by obeying Him. We pray in faith for strength to conquer temptation. We can also develop faith in a particular principle, such as the Word of Wisdom or tithing, by first believing in Jesus Christ strongly enough to obey His commandments. As we live a specific commandment, we learn the truthfulness of it by experience (see John 7:17). We also grow in faith by hearing the word of God (see Romans 10:17) and by reading the word of God (see Helaman 15:7–8).
As we obey God, He blesses us. He gives us power to meet life’s challenges. He helps us change the desires of our hearts. Through our faith in Jesus Christ, He can heal us, both physically and spiritually (see Preach My Gospel , 61–62).
