Mormonism teaches that faith is not just a passive belief, but a principle of action. It is a work that leads to receiving all the gifts and blessings from God. The object of a Mormon’s faith is in their obedience to follow Christ and to carry out the laws and ordinances of the LDS Church.
“Faith is a principle of action and power. Whenever we work toward a worthy goal, we exercise faith. We show our hope for something that we cannot yet see. ..You can exercise faith in Christ when we have an assurance that He exists, a correct idea of His character, and a knowledge that we are striving to live according to His will.” (True to the Faith, p. 54)
“You can strengthen your faith by keeping the commandments. Like all blessings from God, faith is obtained and increased through individual obedience and righteous action. If you desire to enrich your faith to the highest possible degree, you must keep the covenants you have made.” (True to the Faith, p. 55)
Biblical Christianity teaches:
“Faith is being sure of what we hope for and certain of what we do not see.” (Heb. 11:1) For believers, it means making Christ as the object of our faith and trusting or having complete confidence in Him as the Savior from sin. Faith is a receiving instrument through which a person receives the full benefit of what Christ did for all. Faith is a gift received from God through the power of the Holy Spirit. (1 Cor. 12:3) By faith alone, a person is justified before God.
