1. (vv. 22-24) because those who don't won't be saved
2. (vv. 25-27) because time is limited
3. (vv. 28-30) because some who think they're saved will be terribly surprised

FOR FURTHER REFLECTION
1. (vv. 22-24) what does it mean to continually strive to enter the narrow door of salvation? What s the difference between WORKS-based salvation to try to earn your salvation and WORD-based striving that leads to repentance and good works as a result (see also Luke 8:15, Galatians 3:1-9)?

2. (vv. 25-27) The main question we must ask ourselves is not, "DO I know Jesus?" but "Does Jesus know me?" How can we be assured that Jesus KNOWS us (see also Luke 8:15)?

3. (vv. 28-30) Read Isaiah 25:6-8. How does this image of future salvation encourage you to strive to hold onto the words of Jesus in a fallen world filled with difficulties, cares, riches and pleasures that seek to pull us away from God (see also Luke 8:13-14)?
