I am not sure what you are asking. Your wills, is that the same as chances?
God's love for us is perfect, he says that he keeps no records of our wrongs. He continues to put his free gift of grace on the table of our lives, it is up to us to receive it.
So you keep "screwing up and you are a fool", well join the club, that just about describes all of us!!! BTW, Jesus died on the cross for that.
Realize that you are forgiven and allow Jesus Christ to work in your life and He will show you his ways and give you understanding that transcends this physical world!
Welcome to the human race my friend. God will reach any heart that is willing and it is His great pleasure to give you the kingdom of God..
1Co 1:26 For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called:
1Co 1:27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;
1Co 1:28 And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are:
1Co 1:29 That no flesh should glory in his presence.
1Co 1:30 But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:
1Co 1:31 That, according as it is written, He that glorieth, let him glory in the Lord.
In the Bible, a fool is a Godless man. You are not a Godless man; you're a believer who struggles with temptation. We all struggle with temptation. Welcme to the club.
Where the three years is concerned, keep in mind that Jesus often used figures of speech in His teachings. The three years is a figure of speech that indicates an adequate period of time. Remember that Jesus was speaking to people who lived in an agrarian society. They understood the metaphor right away, knowing that three years was a sufficient time to wait for a tree to bear fruit.
