It is difficult to keep looking for the grace of God in times of difficulty but that is exactly what God has commanded us to do. Since all of life is lived by the grace of God then we should look for it all the time, and in every situation, and in the lives of everyone. Of course it is easier to complain and become disgruntled, but the christian life is meant to lived on a different level and from a different perspective by believing in God and his son Jesus Christ. Which would you rather get: Judgment or grace? I am afraid many confessed believers live like they expect judgment rather than grace. Do you? Genesis 29:1-30 gives us ways to understand God's work that will cause us to see grace in Disappointments through seeing divine appointments, believing in God's timing, and living for the benefit of others.
You must believe in Divine appointments. You can see divine appointments in the live of Jacob. He was going to Haran to be with his uncle Laban and all of a sudden he meets his cousin Jacob who, in his heart is still not completely honest, is enamored with Rachael and her beauty. He arrives at a cistern where the shepherds water their flock and Rachael, who is a shepherdess, comes there at the right time to meet Jacob. That is a divine appointment and one that will help you see God's grace in your disappointments if you believe that all appointments are divine ordered
You must believe in the timing of God in your life. You can God's timing in the life of Jacob. Jacob had to wait 14 years to Marry the one he really loved -- Rachael. While he worked for Laban, his uncle for a month, God made sure that that time he proved himself a worker that was worthy of a wage. Even the marriage to Leah, was part of God's timing in Jacob's life. He married one who had better character than Rachael. God protected him, even though his choice of Rachael was made only on outer beauty and not inner qualities of character. Leah was more a woman of character. But through all that he had to wait for God's timing provided for his desires and also protected him from his brother Esau.
Finally you must live for the benefit of others. You can see that Jacob was not use to living for the benefit of others. He did not consider the custom of greeting when he met Rachael and kissed her before he told her who he was. He also disregarded the owner o the cistern and moved the rock and water Rachael's flock. He did not consider it important to abide by the rules that the owner had set down. He also did not understand that (while Laban may have been not completely forthright in his formalized agreement with Jacob) that custom would have had him marry the older of the sisters first before. His passions got away from him.
When we are disappointed we typically try to earn God's blessing by our actions. But according to Titus 3. We cannot do anything to improve our relationship with God except trust in the death of His son Jesus Christ. The more we do that the more we are going to see God's grace in all of life. And the more we recognize divine appoints, God's timing, and live for the benefit of others we will see God's grace in the lives of people around us.
