Jesus did not really try: everything he spoke was in parables, so those with faith would understand him, and know where to follow him; while those with a stubborn heart, would be confounded, and lost.

Matthew 13

10. And the disciples came, and sayd vnto him, Why speakest thou vnto them in parables?

11. He answered, and said vnto them, Because it is giuen vnto you to know the mysteries of the kingdome of heauen, but to them it is not giuen.

1 Corinthians 2

14. But the naturall man receiueth not the things of the Spirit of God, for they are foolishnesse vnto him: neither can he know them, because they are spiritually discerned.
