Jesus was sent to give repentance to Israel which is Gods chosen people of whom all believers are and to forgive our sin! (Acts 5:29-32) 29 Then Peter and the other apostles answered and said, We ought to obey God rather than men. 30 The God of our fathers raised up Jesus, whom ye slew and hanged on a tree. 31 Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins. 32 And we are his witnesses of these things; and so is also the Holy Ghost, whom God hath given to them that obey him.
Scripture teaches us so many times that it is important for us to repent and turn from our sin. God says He will remove our transgressions as far as the east is from the west, and although we do not know that distance we do know it is far enough away from God to forgive us and our sin is removed from His sight! (Psalm 103:10-14) 10 He hath not dealt with us after our sins; nor rewarded us according to our iniquities. 11 For as the heaven is high above the earth, so great is his mercy toward them that fear him. 12 As far as the east is from the west, so far hath he removed our transgressions from us. 13 Like as a father pitieth his children, so the LORD pitieth them that fear him. 14 For he knoweth our frame; he remembereth that we are dust.
Just as the house of Israel was told to repent and turn from their transgressions, we must also today do the same to gain heaven! (Ezekiel 18:30-32). Therefore I will judge you, O house of Israel, every one according to his ways, saith the Lord God. Repent, and turn yourselves from all your transgressions; so iniquity shall not be your ruin. Cast away from you all your transgressions, whereby ye have transgressed; and make you a new heart and a new spirit: for why will ye die, O house of Israel? For I have no pleasure in the death of him that dieth, saith the Lord God: wherefore turn yourselves, and live ye.
It is highly important for us to repent of our sin and transgression because God has the power to destroy us if He chooses to! We see in the story of the potter and the clay that God can do as He pleases and expects us to be obedient to His will. God tells the house of Israel they are as clay in His hands and they should turn from their evil ways. Repentance means a lot in Gods eyes and to be rebellious only hurts ourselves. In the following passage we see that even God repents and this should be a lesson to us that we should repent as well! (Jeremiah 18:6-12) 6 O house of Israel, cannot I do with you as this potter? saith the LORD. Behold, as the clay is in the potter’s hand, so are ye in mine hand, O house of Israel. 7 At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy it; 8 If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them. 9 And at what instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant it; 10 If it do evil in my sight, that it obey not my voice, then I will repent of the good, wherewith I said I would benefit them. 11 Now therefore go to, speak to the men of Judah, and to the inhabitants of Jerusalem, saying, Thus saith the LORD; Behold, I frame evil against you, and devise a device against you: return ye now every one from his evil way, and make your ways and your doings good. 12 And they said, There is no hope: but we will walk after our own devices, and we will every one do the imagination of his evil heart.
God takes no pleasure in the death of the wicked nor does He want any one of us to remain in our sins. This is why He sent His only begotten Son to save us from destroying ourselves. We see this great lesson when God says to Israel why do you want to destroy yourself? (Ezekiel 33:10-20).
