In Matthew 21 we read that Jesus told two of His disciples to go get Him a donkey and a colt. The donkey represents the subborn things that He is calling for us to let go of and the colt represents the places God wants to take us where we have never been. Jesus told the disciples to tell the owner "the Lord has need of them.
Interesting enough that Jesus already knew the location and conversation that would take place before they even happened. This is such a reminder that we serve a God of destiny. He is a God who knows our end from the begining.
