After Nehemiah heard about the desperate condition of the Jews who had returned from exile to Jerusalem, his heart was burdened (Neh. 1:3-4). By getting his attention in this way, the Lord could reveal what He wanted Nehemiah to do. Scripture doesn't spell out the man's reaction on realizing that he was to be a part of the solution, but we can imagine a sense of inadequacy probably engulfed him. How could he possibly help? He wasn't even near Jerusalem, and as a servant of the king, he didn't have the freedom to pack up and leave.
But whenever God puts a burden on our hearts, He will open a door to accomplish His will. In this case, the Lord used Nehemiah's sad expression and desperate prayer to prepare a pagan king to send him on his mission.
How do you respond when you sense the Lord is calling you to a task that seems beyond your abilities? Do you list all the reasons you can't possibly do it? God already knows everything about you and the situation. He's not asking your permission to proceed; rather, He is calling you to move forward with faith and obedience. He didn't make an error in choosing you for the task, but you will make a huge mistake if you refuse to do it.
God will equip you for whatever He calls you to do. Because the Holy Spirit dwells within every believer, we have all we need to fulfill the Lord's mission. Instead of letting inadequacy hinder you from obeying, let it drive you to your knees so you can arise with renewed insight and power.
