God had a purpose for the donkey
. . . when he sent two disciples to fetch it. We can learn something from this animal.
The untamed colt was tied by the door on the outside as Christ said it would be. If you've never accepted Jesus as your Savior, you are on the outside of Christ, the door to heaven. You are tied to sin, bound by a sinful life style. Some unbelievers make excuses like, that's just how I am. I was born that way. That's why they need to be born again.
The colt was at a cross road where two ways met. If you are tied to sin, you too are at a cross road, and its decision time. Do you go man's way -- Satan's way, your way or God's way?
Isaiah55:6 Seek ye the Lord while He may be found; call ye upon him while He is near:
They untied the mule and brought it to Jesus. To be free from your sins, you have to come to Jesus. God's grace for salvation gives you a new walk. Christ is the truth, the way, the door, and the difference maker.
