As an organization they came, and still come, presenting a gift offering in righteousness. And their offering is “gratifying to Jehovah, as in the days of long ago and as in the years of antiquity.” (Malachi 3:4) It was these that Jehovah prophetically invited: “‘Bring all the tenth parts into the storehouse, that there may come to be food in my house; and test me out, please, in this respect,’ Jehovah of armies has said, ‘whether I shall not open to you people the floodgates of the heavens and actually empty out upon you a blessing until there is no more want.’”​—Malachi 3:10.

12. What kind of spiritual offerings and sacrifices do Christians make?

¹² For them, offerings are outstandingly of a spiritual kind. (Compare Philippians 2:17; 2 Timothy 4:6.) For example, Paul spoke of the preaching work as an offering when he said: “Through him let us always offer to God a sacrifice of praise, that is, the fruit of lips which make public declaration to his name.” He pointed to another spiritual kind of sacrifice when he urged: “Do not forget the doing of good and the sharing of things with others, for with such sacrifices God is well pleased.” (Hebrews 13:15, 16) When parents encourage their children to enter the pioneer service, they may be said to be offering them to Jehovah, much as Jephthah offered his daughter as “a burnt offering” to God, who had given him the victory.​—Judges 11:30, 31, 39.
