Matthew 7:13-14
“Enter by the narrow gate. For the gate is wide and the way is easy[a] that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard that leads to life, and those who find it are few.

The best way to learn, however, is not to keep reading and studying until you feel super-confident, with no doubts left regarding your ability.
