The methods that God uses to get things done are difficult to understand. People say that God works in mysterious ways. His ways are not so much "mysterious" as they are confusing and complex. God is clear about the things He desires to do. It is the manner in which He accomplishes those things that baffles the human mind. The Bible teaches that God's ways are not our ways, and His thoughts are not our thoughts. The prophet Isaiah wrote that His ways and thoughts are as far from normal human thoughts as we are from the stars! That's a great distances. The thing that makes God so unique in His thinking and methodology to accomplish His will is that He is omniscient. He knows everything! He knows the beginning from the end, and that puts Him at the greatest position of advantage. Since He knows everything that everyone is going to do, and can even examine the motives that all have for doing those things, God can also exercise His sovereignty to see that His will is done - no matter how odd, unconventional, or nontraditional His will or methods may seem.
This truth is powerfully presented in the testimony of Jacob "stealing" the blessing of Esau. There are many people who have read this testimony and question God's judgment and involvement in the circumstances. Since it seems as if Jacob and his mother are being deceptive, it appears as if God approves deception. One must consider the scriptures in the full context of God's Word, according to His will and promises in order to understand God's purposes. For example, in Genesis 27:1-17 the Bible explains the setting for the deception that Rebekah and Jacob participate in. The testimony begins by explaining the physical condition of Isaac. He is old and going blind. Understanding his position, Isaac sought to bless his sons according to the traditions of the people at the time. Traditions called for the father to bless the oldest son first as the heir of all of the father's possessions. Thus, Isaac asked Esau to go out, hunt some good food, cook it up, and bring it to him before he died in order that he could bless his oldest son Esau in the manner that the people were accustomed, before he died.
Genesis 27:1-17 explains that Isaac's wife Rebekah heard the conversation that took place between Isaac and Esau. She sought to respond in what has been described as "deception." The scriptures explain that Rebekah called for Jacob, and explained a plan that she had come up with. Her plan was to have Jacob slaughter a goat. She would cook the goat in a special way that Isaac enjoyed. She then wanted Jacob to dress up as Esau, and present the food to Isaac in order that he would receive Esau's blessing. Jacob expressed a certain amount of concern. He brought up the point that Esau was hairy (hence the name 'Esau,' which means 'hairy'). Rebekah told Jacob not to worry about it, cut some goat hair, and placed it on the arms and neck of Jacob to confuse Isaac who was going blind. The plan was to have Jacob appear as Esau before Esau returned in order that the blessing would be given to Jacob, and Jacob would be the heir of Isaac.
While this plot might seem like deception from a human perspective, one must consider the perspective of God. One cannot examine the testimony of Genesis 27:1-17 without considering the testimony of Genesis 24:23. In Genesis 24:23 Rebekah inquired of the Lord about her pregnancy. She knew that there was quarreling going on in her womb and didn't understand. God revealed that Rebekah was pregnant with twins and that one was a wild man, and the other more mild. God prophesied and explained at that time that the older son would serve the younger son. God explained that Esau would serve Jacob. God explained that Jacob would be the heir of Isaac instead of Esau. God explained that Jacob would be the heir of His own promises rather than Esau.
One must then recall the events of Genesis 25:27-34. In this portion of scripture, the Bible explains why God was willing to allow the older to serve the younger. Genesis 25:27-34 explains that Esau was so desperate for a bowl of soup that he was willing to sell his birthright to Jacob. Esau plainly stated, "What is my birthright to me?" The scriptures reveal that Esau had no appreciation for his birthright as the heir of Isaac - especially the promises that God made to Abraham. Esau was more concerned about fulfilling his flesh with food than receiving the blessing of God. Later in scripture the Bible explains that Esau married two Hittite women - women that worshiped false gods and idols and not the living God. Esau didn't care about the things of God, and so God leveraged His knowledge of such things to work against the traditions of men to accomplish His will and make Jacob the heir of His promises.
When one simply examines the testimony presented in Genesis 27:1-17, it appears as if God is accepting of deception since the Lord does not rebuke Jacob or Rebekah for their actions. In fact, Romans chapter 9 clarifies the situation in that God did not rebuke Rebekah or Jacob because God Himself chose Jacob as the heir to His promises "by election." Since God understood the character and temperament of Esau before he was born (since God knows all things), He knew He didn't want to make Esau the heir of His promises since Esau didn't care about His promises. Therefore, while people might consider the actions of Rebekah and Jacob in Genesis 27:1-17 as "deceptive," God would simply examine those actions as the necessary actions to accomplish His will. If the actions of Rebekah and Jacob had been sinful, then God would have addressed it as such.
So how does one digest this information? How does the human mind receive such a testimony? The point is that God knows all things and uses all of that knowledge to His advantage to accomplish His will. Since people cannot determine the beginning from the end, and has little to no understanding of life's circumstances, one must simply trust in the Lord. One must always remember that things might not always be as they seem. One must be careful how one measures circumstances because it is impossible to know how God will use circumstances to do His will. We see things one way with limited information. God sees things another way in His infinite wisdom. To put things simply, lean not on your own understanding; rather trust in the Lord with all your heart!
