Some time ago I spoke at Horn Creek Lodge in Horn Creek, Colorado not too far from Colorado Springs. If you have never been there you need to go. It is a great place to spend a week. The mountains are at your front door and the deer walk up to your back door. The food is delicious and the accommodations are delightful. But you know what is interesting about this place? In order to get there everyone has to take the same road because there is only one road into Horn Creek, Colorado.
The point Christ is making is there is enough room in heaven for all the ones who are going there but to get there everyone has to take the same road. You have to come to God as a sinner, recognizing that Christ died and arose and put your trust in Christ alone as your only way to heaven because He is the way, the truth, and the life.
