The writer of the book of Hebrews calls upon us to offer two types of sacrifices to God. First, we are to offer “the sacrifice of praise” which we do in song and prayer. In the Old Testament God was praised with instruments of music (Psalm 150) but under the Christian system we offer “the fruit of our lips.” (Hebrews 13:15)
Second, we offer the sacrifice of good works. We are to “do good” and to “share” for God is pleased with such sacrifices. (Hebrews 13:16 NKJV) Whenever we help our fellow man, God views it as an offering to Him. There is a proverb which says: “He that hath pity upon the poor lendeth unto the Lord” then adds this: “And that which he hath given will he pay him again.” (Proverbs 19:17) Jesus said, “Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.” (Matthew 25:40)
Let us always remember these two sides to the Christian life. We must offer our worship to God and also live lives of helping others.
