My thought was that to follow Jesus, one must be willing to forsake all and never look back. It is total surrender to Him. Jesus' disciples left their nets to become fishers of men.
Luke 14:33 So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.
It is definitely a choice, not an accident. I believe that this was the spirit of Abraham...
Hebrews
11:8 By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went.
11:9 By faith he sojourned in the land of promise, as [in] a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise:
11:10 For he looked for a city which hath foundations, whose builder and maker [is] God.
11:14 For they that say such things declare plainly that they seek a country.
11:15 And truly, if they had been mindful of that [country] from whence they came out, they might have had opportunity to have returned.
11:16 But now they desire a better [country], that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.
