Matthew 26:24 The Son of Man indeed goes just as it is written of Him, but woe to that man by whom the Son of Man is betrayed! It would have been good for that man if he had not been born.”
When you know your purpose there are things that you know you can do but can’t because of your purpose. When you make decisions that are line with your purpose, those decisions might make you unpopular because people are used to complying to a group behavior. Those whose who have money give thought in their giving and those without money just give away money because they feel good about it. What we love might not be for us.
When you serve a master, it’s not that you are doing better than others to be recognized, you are just available to be used. Joshua did everything that the other people with Moses were doing, but there was something extra that the he did in his own capacity because he knew he was not the same as the others. Exodus 33:11 So the LORD spoke to Moses face to face, as a man speaks to his friend. And he would return to the camp, but his servant Joshua the son of Nun, a young man, did not depart from the tabernacle.
Knowing your purpose helps helps you decide between good and godly. Even though Jesus knew that Judas will betray Him, he kept him close because He understood His purpose here on earth. Knowing his purpose made Him think right and sometimes his decisions were not popular. Matthew 16:21-22 From that time Jesus began to show to His disciples that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and be raised the third day. Then Peter took Him aside and began to rebuke Him, saying, “Far be it from You, Lord; this shall not happen to You!”
