"***** Human Effort Essential The agency of the Spirit of God does not remove from us the necessity of exercising our faculties and talents, but teaches us how to use every power to the glory of God. The human faculties, when under the special direction of the grace of God, are capable of being used to the best purpose on earth. Ignorance does not increase the humility or spirituality of any professed follower of Christ. The truths of the divine word can be best appreciated by an intellectual Christian. Christ can be best glorified by those who serve Him intelligently. The great object of education is to enable us to use the power which God has given us in such a manner as to represent the religion of the Bible and promote the glory of God. CT 361"
"And unto one he gave five talents, to another two, and to another one; to every man according to his several ability; and straightway took his journey."
The EGW passage directly discusses using talents to the glory of God, which is the central theme of the parable of the talents in Matthew 25:15. The verse is the basis for the principle EGW is discussing.
"We are indebted to Him who gave us existence, for the talents that have been entrusted to us, and it is a duty we owe our Creator to cultivate and improve these talents. Education will discipline the mind, develop its powers, and understandingly direct them, that we may be useful in advancing the glory of God. CT 361.2"
"For the kingdom of heaven is as a man travelling into a far country, who called his own servants, and delivered unto them his goods. And unto one he gave five talents, to another two, and to another one; to every man according to his several ability; and straightway took his journey. Then he that had received the five talents went and traded with the same, and made them other five talents. And likewise he that had received two, he also gained other two. But he that had received one went and digged in the earth, and hid his lord’s money. After a long time the lord of those servants cometh, and reckoneth with them. And so he that had received five talents came and brought other five talents, saying, Lord, thou deliveredst unto me five talents: behold, I have gained beside them five talents more. His lord said unto him, Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord. He also that had received two talents came and said, Lord, thou deliveredst unto me two talents: behold, I have gained two other talents beside them. His lord said unto him, Well done, good and faithful servant; thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord. Then he which had received the one talent came and said, Lord, I knew thee that thou art an hard man, reaping where thou hast not sown, and gathering where thou hast not strawed: And I was afraid, and went and hid thy talent in the earth: lo, there thou hast that is thine. His lord answered and said unto him, Thou wicked and slothful servant, thou knewest that I reap where I sowed not, and gather where I have not strawed: Thou oughtest therefore to have put my money to the exchangers, and then at my coming I should have received mine own with usury. Take therefore the talent from him, and give it unto him which hath ten talents. For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath. And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth."
This EGW passage is clearly based on the parable of the talents. It speaks of being entrusted with talents and the duty to cultivate and improve them, directly echoing the parable's message.
