What kind of gate did Jesus tell people to enter through?

Answer: The narrow gate

Jesus said wide is the gate that leads to destruction, but small is the gate and narrow the way that leads to life.

“Enter through the narrow gate. For wide is the gate and broad is the way that leads to destruction, and many enter through it. But small is the gate and narrow the way that leads to life, and only a few find it.”— Matthew 7:13-14 (BSB)
