Even when Adam and Eve sinned by disobeying what the Lord had commanded them God still loved them. He still wanted to communicate with them.
When the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was desirable to make one wise, she took from its fruit and ate; and she gave also to her husband with her, and he ate. Then the eyes of both of them were opened, and they knew that they were naked; and they sewed fig leaves together and made themselves loin coverings. Genesis 3:6,7
They hid from Him but God did not hide from them.
They heard the sound of the Lord God walking in the garden in the cool of the day, and the man and his wife hid themselves from the presence of the Lord God among the trees of the garden. Genesis 3:8
They hid from God and knew they were naked so they made coverings out of fig leaves for themselves. For the first time they were afraid.
Then the Lord God called to the man, and said to him, “Where are you?” Genesis 3:9
However, even in their fear they were honest with God about what they had done. They did not deny what they had done.
He said, “I heard the sound of You in the garden, and I was afraid because I was naked; so I hid myself.” Genesis 3:11
The Lord provided for them because He loved them. In spite of their sin the Lord knew that they needed help. The Lord gave them what they needed.
The Lord God made garments of skin for Adam and his wife, and clothed them. Genesis 3:21
Cain, on the other hand, denied his sin to the Lord.
Then the Lord said to Cain, “Where is Abel your brother?” And he said, “I do not know. Am I my brother’s keeper?” Genesis 4:9
Of course the Lord knew what Adam and Eve had done before He asked them and He knew what Cain had done. He also knows what each of us has done but He wants to know if we will be honest with Him.
He said, “What have you done? The voice of your brother’s blood is crying to Me from the ground. Now you are cursed from the ground, which has opened its mouth to receive your brother’s blood from your hand. When you cultivate the ground, it will no longer yield its strength to you; you will be a vagrant and a wanderer on the earth.” Genesis 4:10-12
Adam and Eve repented of their sin and sought to obey God from that time on. Cain seemed to be sorry for the consequences rather than sorry for what he had done. There does not seem to be any desire for obedience.
Cain said to the Lord, “My punishment is too great to bear! Behold, You have driven me this day from the face of the ground; and from Your face I will be hidden, and I will be a vagrant and a wanderer on the earth, and whoever finds me will kill me.” Genesis 4:13,14
The Lord still showed Cain mercy and provided for him. He did not need coverings as Adam and Eve did after they sinned but he needed protection. The Lord provided protection for Cain. The Lord still loved Cain and heard his cry for help.
So the Lord said to him, “Therefore whoever kills Cain, vengeance will be taken on him sevenfold.” And the Lord appointed a sign for Cain, so that no one finding him would slay him. Then Cain went out from the presence of the Lord, and settled in the land of Nod, east of Eden. Genesis 4:16a
There are still two kinds of people. There are those who repent of their sins and turn to the Lord and there are those who are sorry for the consequence of their sins but there is no desire to change. Peter wept over his sin when he denied the Lord and grieved over what he had done.
And Peter remembered the word which Jesus had said, “Before a rooster crows, you will deny Me three times.” And he went out and wept bitterly. Matthew 26:75
Judas on the other hand, was sorry for what he had done, but there was no repentance.
Then when Judas, who had betrayed Him, saw that He had been condemned, he felt remorse and returned the thirty pieces of silver to the chief priests and elders, saying, “I have sinned by betraying innocent blood.” But they said, “What is that to us? See to that yourself!” And he threw the pieces of silver into the temple sanctuary and departed; and he went away and hanged himself. Matthew 27:3-5
The Lord loved both Peter and Judas. The Lord loves each of us and has shown us His kindness over and over again desiring that we will repent and come to Him.
Or do you think lightly of the riches of His kindness and tolerance and patience, not knowing that the kindness of God leads you to repentance? Romans 2:4
Peter was restored in his relationship with the Lord and Judas was not. The Lord came to restore us. He loves us but He wants us to not only be sorry for what we have done but to turn away from our sin and turn to Him with all of our heart. He wants us to love Him. He wants our hearts. Love is more than just being sorry for what you have done. Love is changing and going in a different direction so you won’t do the same thing. If you love someone then you will get help rather than continuing to hurt them over and over again. Love is more than just being sorry. Love is repentance and changing.
