How to make every effort to enter through the narrow door

Lk 13.24: “Exert every effort to enter through the narrow door, because many, I tell you, will try to enter and will not be able to” (NET).

Let us exert every effort:

1. In knowledge, Prov 2.1-5.
2. In prayer, Col 4.12.
3. In meeting together, Heb 10.25; 12.1.
4. In the gospel, Phil 1.30.
