[1 Samuel 18: 8 Saul was very angry; this refrain displeased him greatly. “They have credited David with tens of thousands,” he thought, “but me with only thousands. What more can he get but the kingdom?]
Often times we compare what we do with others. Comparison is good but it must not get into our heads. God has given us a measure of what we are able to achieve. Others can do more while others less. When comparison with others becomes our way of life, it can land us in more problems. In the scripture above, when king Saul heard women crediting David to have killed ten thousands and him only a thousand instead of celebrating together with him, he got upset. He wanted to be credited more than David but he failed to kill Goliath. This made him to make sure David was brought down. But the hand of God was upon David and he survived all the plans of King Saul. In the end disaster came upon Saul.
My brothers and sisters, we can not all achieve the same things at the same time. Some people will do more while others less. God knows what is best for you. Do not compare your achievement with others. You do not know how they do it and what they have to reach where they are. Celebrate with them when they prosper and one day your time to celebrate will come.
