One of the phrases in the passage I preached on (1 Pet. 4:10-11) says, “Whoever speaks is to do so as one who is speaking the utterances of God (verse 11a). Every believer in the Lord Jesus Christ has been given at least one gift by God in HIs grace. We’re to use those gifts well as good stewards. Those gifts are divided by Peter into two broad categories: speaking and serving.
Those who have speaking gifts (such as teaching, preaching, and exhortation) are to proclaim God’s Word and not their own. Charles Spurgeon said,
Reckon that every sermon is a wasted sermon which is not Christ’s Word. Believe that all theology is rotten rubbish which is not the Word of the Lord. Do not be satisfied with going to a place of worship and hearing an eloquent discourse, unless the sum and substance is the Word of the Lord. My brothers and sisters, whether you teach children or their parents, do not think you have done any good unless you have taught the Word of the Lord. For saving purposes we must have the Lord’s Word, and nothing else.
