Key Points for Students

God created human beings for the following reasons:

  1. To know Him

  2. To love Him

  3. To serve Him

  4. To be happy with Him forever

Our first parent, Adam and Eve enjoyed a life of complete happiness before they committed sin. They never knew what pain nor sorrow was until they disobeyed God. In short, both were perfect beings until they committed the sin of disobedience against God.

Disobedience may simple be defined as the failure to obey rules, command or someone in authority.

Adam and Eve were the first human beings to disobey God.

Please read more on the biblical account of first human disobedience here

CRS

Adam and Eve were able to commit sin (disobey God's command) because God had given them that special gift of free will.

The events written in Genesis 3:1-13 presents the story of the first human disobedience.

Now the snake was the most cunning animal that the Lord God had made. The snake asked the woman, 'Did God really tell you not to eat fruit from any tree in the garden?'

Genesis 3:1

Moral Lesson: The devil can come in any form and can tempt any man, woman, boy or girl, as far as he or she is of the age of reasoning.

Sometimes, satan creeps into one's life by asking simple questions. Notice that the snake (satan) did exactly this when it approached Eve to tempt her. To this end, we need to be at alert prayerfully because the evil one can tempt any human in any situation, place and at any point in time
