Standing on the edge of the Promised Land, the Israelites were overcome by fear. The size and strength of the enemy contrasted sharply with their own weakness and inability. Because we're human, everyone at times will experience inadequacy and the uncomfortable feelings that accompany it. The issue you and I face is not whether we are sufficient for a task, but how we will respond when a challenge is beyond our capabilities.
Like the children of Israel, we can give in to fear and then focus on the expectation of certain failure. As the obstacle grows in our minds, our feet run in the opposite direction, away from the challenge and toward safety. However, turning away from the task that God has given us will lead us not to security but into bondage. By allowing fear to control our choices, we'll become chained to feelings of inadequacy, which will shape our future decisions and, ultimately, our destinies.
As a result of their refusal to trust the Lord and move forward to conquer the land, the Israelites were consigned to wander in the wilderness for 40 years. The men who did not believe God's promise never saw the land that He wanted to give them. Opportunities are always lost when we let fear overrule our faith.
When God calls you to a task beyond your abilities, instead of giving in to your feelings, choose to rely on what you know about Him and His promises. By moving forward in faith despite your inadequacy, you will discover the Lord's faithfulness. He always empowers us for the works He assigns.
