ANSWER: They are not the source of life, but rather the means of grace through which, when used with faith in Christ, the Holy Spirit may impart and sustain life. Baptism is the outward sign of the Spirit's inward work The Lord's Supper is a memorial of Christ's great love manifested in voluntarily dying for us. Whatever brings this event vividly to the mind of the believer is a means of grace. We should beware of resting in the symbol instead of the thing signified. Thousands of ceremonialists are trusting for salvation in symbols instead of the Savior — in the shadow instead of the substance. The sacraments alone, though administered by priests who claim to be ordained by bishops in succession back to the apostles, are not saving. Only Christ saves.
