The people didn’t wait on the wall to miraculously build itself. They didn’t wait on someone else to come in and build it for them. They. built. it.
Following the Lord’s will takes effort. If we are going to grow as Christians, if the kingdom of God is going to be added to then we need to get to work.
Pray. Study. Listen. Move forward with the ministry he has put on your heart instead of trying to give it someone else. Be a responsible Christian. You, others and God’s kingdom will benefit from your work for the Lord.
