As Christians, we believe that we are God's children. If we believe that we are God's children, we also believe that God is our father, who cares for and guides us until we understand who we are. In this case, we must believe that we have grown with God step by step since the beginning. So, when we talk about sin—the "absence of a good relationship with God"—we must also talk about grace because we are growing up under God's Love. We recognize that we are sinners when we notice how excellent and grateful God's Love is to us, and when we face that, we feel more guilty about ourselves. In other words, we believe that our understanding of God's Love through our life experiences helps us to recognize that we are sinners but that we are also children of God whom God always loves in the relationship between God as a father and human beings as his children. That is one way to understand where sin originated.
God created heaven and earth out of his Love in the beginning, separating the material and immaterial and gathering them together in one place. God filled it with creatures of all kinds that are good to one another. When God created things, they were already good, but to make it complete, he created humans in his image to care for and fulfill all things so that humans become the one of all goodness. The history of humanity began there.
Humans progress as God's children, one step at a time. The first step is that God always keeps humans as "babies" under his wings. Since the beginning of time, humans have attempted to imitate what God did; to imitate what God said, to converse with God, to learn how to think, and to make friends with God and others. Then humans began to learn about themselves, their surroundings, and the presence of God's Love in their midst. God is always with them in this relationship, guiding and accompanying them to be more vigorous in body and feeling so that they can grow in their knowledge. Whatever humans did at the time was always geared toward learning from God, and as a result, humans can be said to be the 'image of God.'
In the second step, God loves humans as "teenagers," guiding them; he is always with them, but he has given them more opportunities to stand with their understanding. In this case, humans grew according to their nature—feelings, and thoughts—so God also provided some rules to help humans maintain good discipline and be prepared to face the conditions around them. As a result, God brought humans to know his world, the earth, so that humans could learn to love the other creators. Humans began to use their knowledge to think about themselves and discover their way of life—their identity compared to other things. Humans were still labile in this condition, facing new things in their lives, to know and follow the rules of God; what were the necessary things for their life, or they follow their desire.
In the third step, God continues to share his unconditional Love with humans as an "adult," guiding them with the Love planted within them. God gave humans more freedom to be full humans as God's children. As a result, humans were more stable in using their knowledge, feelings, and beliefs that they were already an "image of God" in this world. They began looking for God's Love's greatness with them in this relationship from the beginning. Through the illumination of God's Love in them, they discover that their entire life was a creation of God's Love. They realized that they had frequently done innocuous things to God but had always loved them. They felt their relationship with God, who accompanied them on their journey to know His Love, but they frequently followed what they thought was good. So on.
Finally, humans recognized the greatness of God's Love in their lives and realized that, since the beginning, they had done many things contrary to God's Love, but God had always loved them, so humans felt guilty about-facing God. According to this viewpoint, the more they felt God's Love, the more guilt they felt. As a result, the origin of sin began with the realization of how great God's Love was and what humans had done in their relationship with God.
In summary, as humans, they grew step by step as bodies, feelings, and understanding; humans began to recognize the greatness of God's Love. And then they noticed their guilt—how frequently they broke their relationship with God, misunderstand God's Love, and yet God still loves them. Realizing our situation through God's Love, they believed they have already committed sins and cut themselves off from God and his goodness. The origin of sin began at this point.
