Summary: The Sermon on the Mount is not just a nice collection ethical rules. There is a clear invitation for you to make the two most important decisions of your life. These are the decisions of a high impact Believer.
"Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. But small is the gate and narrow the road that leads to life, and only a few find it" (Matthew 7:13-14 (quickview)  NIV).
Throughout life we have to make a number of very important decisions. The Sermon on the Mount is not just a nice collection ethical rules. There is a clear invitation for you to make two decisions. First, what you are going to do with Jesus Christ? And second, if you choose to follow him, what kind of follower will you be?
Jesus starts by talking about two roads. There’s a small gate and a narrow road - and there’s a wide gate and a broad road.

A) WILL YOU FOLLOW JESUS?
1. What’s the difference between the two roads?
a. The broad road
The broad road is clearly a place where there are no boundaries and you can do whatever you like. You don’t have to worry one iota about the standards that Jesus has just set out in the Sermon on the Mount.
But the problem with the broad road is that where there are no boundaries, people get hurt.
b. The narrow road
This is the road that Jesus has just outlined in the Sermon on the Mount. It’s a life surrounded by loving boundaries. Life on the narrow road is not just difficult, it’s actually impossible to live it without Jesus’ help and intervention in your life.
2. Where do the two roads lead?
a. The Broad Road
In v13, Jesus warns us that the broad road leads to “destruction.” Jesus says, if you want to live without his loving boundaries guiding your life you will be destroyed. Now, that’s not a threat, it’s a loving warning.
b. The Narrow Road
The destination for those who choose the narrow road is eternal life (v13).
3. Who is on the two roads?
a. The broad road
Sadly, the broad road with the wide gate has “many” (v13) people on it.
b. The narrow road.
Those who have the courage to stand for Jesus even against popular opinion; these are the people that Jesus says are on the narrow road.
4. How do I get into each gate?
If you’re on the broad road you don’t have to do anything in order to stay on it. But if you want to get off the broad road and enter a new life with Christ through the narrow gate – you must surrender your whole life to Jesus Christ.
Friends, this is the single most important question you could ever answer in your life.
B. WHAT KIND OF JESUS FOLLOWER WILL YOU BE?
The second most important question is this – what kind of Christ follower will you be?
a. Will you be a high impact Believer?
Why is this question so important? Because the broad road is packed with people who desperately need you to be a “high impact” – “salt and light” kind of Christian. The kind of Christian Jesus has been describing throughout the Sermon on the Mount.
Ephesians 5:1 (quickview)  says, – “Be imitators of God,” God is a high impact God. God is a missionary God. As the man Jesus Christ, God came to seek and to save what was lost. The Bible says that God wants you to be like that.
