The Savior completely resisted Satan's Temptations to misuse His divine power--Through Fasting

If he lives the principle often enough, it will bring the wonderful effects in his own life, as promised by the Lord. He will have the spiritual blessing of power to receive inspiration and greater capacity to resist temptation.

We do not know all the reasons why Jesus Christ went into the wilderness to fast and to pray. But we know at least one of the effects: the Savior completely resisted Satan’s temptations to misuse His divine power.
