Jesus did not receive baptism as a confession of guilt on His own account. He identified Himself with sinners, taking the steps that we are to take, and doing the work that we must do. His life of suffering and patient endurance after His baptism was also an example to us.
Upon coming up out of the water, Jesus bowed in prayer on the river bank. A new and important era was opening before Him. He was now, upon a wider stage, entering on the conflict of His life. Though He was the Prince of Peace, His coming must be as the unsheathing of a sword.... No one upon earth had understood Him, and during His ministry He must still walk alone. Throughout His life His mother and His brothers did not comprehend His mission. Even His disciples did not understand Him. He had dwelt in eternal light, as one with God, but His life on earth must be spent in solitude.... Alone He must tread the path; alone He must bear the burden. Upon Him who had laid off His glory, and accepted the weakness of humanity, the redemption of the world must rest. He saw and felt it all, but His purpose remained steadfast. Upon His arm depended the salvation of the fallen race, and He reached out His hand to grasp the hand of Omnipotent Love.—The Desire of Ages, 111.
Jesus might have remained at the Father’s side. He might have retained the glory of heaven, and the homage of the angels. But He chose to give back the scepter into the Father’s hands, and to step down from the throne of the universe, that He might bring light to the benighted, and life to the perishing.—The Desire of Ages, 23. WGD 245
The same spirit and principles that one brings into the daily labor will be brought into the whole life. Those who desire a fixed amount to do and a fixed salary, and who wish to prove an exact fit without the trouble of adaptation or training, are not the ones whom God calls to work in His cause. Those who study how to give as little as possible of their physical, mental, and moral power are not the workers upon whom He can pour out abundant blessings. Their example is contagious. Self-interest is the ruling motive. Those who need to be watched and who work only as every duty is specified to them, are not the ones who will be pronounced good and faithful. Workers are needed who manifest energy, integrity, diligence, those who are willing to do anything that needs to be done. MH 499
And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Matthew 3:15, KJV
