The Loving Programmer wrote and downloaded human programs with free will. Free will gives us the ability to make decisions.
Every decision moves us in one of two ways. Some decisions move us closer to God. Other decisions move us away from God. We freely choose to move toward, or away from, God and joy.
Every human program is beset with distractions. If we let them, distractions may distract us from God and from saving our soul. Why would anyone want us to lose our soul?
Souls have great value. God loves them. Satan hates them. God wants each human soul to live with Him in joy, forever. Fallen angels want to corrupt us so that we will reject God and be sent where they can torment us forever.
God, His Saints, Angels, and Church offer souls an eternity of joy. Souls may choose to save themselves by believing in The Loving Programmer. Then, they must choose to obey the operating instructions He provided for those who want to get to Heaven. Human programs who choose to believe and obey sufficiently will have eternal joy.
Satan and his fallen angels are living errors in spiritual form. They distract people from God and His promise of eternal joy. Then, they strive to corrupt the distracted human programs with error. During the life-long process, evil spirits work to download living errors of pride, envy, greed, gluttony, anger, lust, and sloth into human programs. They want the human programs to choose to reject The Loving Programmer Who gave them life.
At Judgment Day, The Loving Programmer separates the human programs into two groups. They have been compared to wheat and weeds, as well as to sheep and goats. The former may live in joy forever. The latter may not.
Catholic Fundamentalism understands that we need to develop a sense of urgency in moving in the right direction. It is important to begin believing and obeying soon because we never know when our soul will leave its mind and body and go to Judgment. After Judgment, we want to continue moving toward God, not into the eternal and agonizing opposite.
