Sow a character and you reap a destiny. Character, like fruit, doesn't grow overnight. It takes a lifetime. Jesus connects soundness with good fruit. Something is sound when it is free from defect, decay, or disease and is healthy.
Good fruit is the result of sound living living according to moral truth and upright character.
The fruits of falsehood produce an easy religion which takes the iron out of religion, the cross out of Christianity, and any teaching which eliminates the hard sayings of Jesus, and which push the judgments of God into the background and makes us think lightly of sin. By being true true to God, his word, and his grace. Those who are true to God know that their strength lies not in themselves but in God who supplies the grace we need to live as his disciples. The fruit of a disciple is marked by faith, hope and love, justice, prudence, fortitude and temperance. O Father, give us the humility which realizes its ignorance, admits its mistakes, recognizes its need, welcomes advice, accepts rebuke.
