Voluntary offerings and the tithe constitute the revenue of the gospel. Of the means which is entrusted to man, God claims a certain portion—a tithe; but He leaves all free to say how much the tithe is, and whether or not they will give more than this. They are to give as they purpose in their hearts. But when the heart is stirred by the influence of the Spirit of God, and a vow is made to give a certain amount, the one who vowed has no longer any right to the consecrated portion. He has given his pledge before men, and they are called to witness to the transaction. At the same time he has incurred an obligation of the most sacred character to co-operate with the Lord in building up His kingdom on earth. Promises of this kind made to men would be considered binding. Are they not more sacred and binding when made to God? Are promises tried in the court of conscience less binding than written agreements with men? (5T 149.1) MC VC

When the divine light is shining into the heart with unusual clearness and power, habitual selfishness relaxes its grasp, and there is a disposition to give to the cause of God. None need expect that they will be allowed to fulfill the promises then made without a protest on the part of Satan. He is not pleased to see the Redeemer’s kingdom on earth built up. He suggests that the pledge made was too much, that it may cripple them in their efforts to acquire property or gratify the desires of their families. The power Satan has over the human mind is wonderful. He labors most earnestly to keep the heart bound up in self. (5T 149.2) MC VC
