Food for thought:
Sodom and Gomorrah: If infants and children are not accountable, why did God count them among the wicked and allow them to be killed? God said He would spare the 2 cities if there were any who were righteous in them. He spared no one but Lot and his family. Those who died, whoever they were and no matter what age, were counted among the wicked. If infants and children are pure and sinless, how could this happen?
Gen 18:23 Abraham said: “Will you sweep away the righteous with the wicked? Will you really sweep it away and not spare the place [Sodom] for the sake of the fifty rightous people in it? 25 Far be it from You to do such a thing… 26 The Lord said, “If I find fifty righteous people in the city of Sodom, I will spare the whole place for their sake.”
Gen 19:12 The two men said to Lot, “Do you have anyone else here – sons-in-law, sons or daughters, or anyone else in the city who belongs to you? Get them out of here, 13 because we are going to destroy this place. The outcry to the Lord against its people is so great that He has sent us to destroy it.”
Great Flood: If infants and children are not accountable, why did God count children among the corrupt and allow them to be killed?
Gen 6:11 Now the earth was corrupt in God’s sight and was full of violence. 12 God saw how corrupt the earth had become, for all the people on earth had corrupted their ways. 13 So God said to Noah, “ I am going to put an end to all people, for the earth is filled with violence because of them. I am surely going to destroy both them and the earth. “
Punishment of the Israelites: If infants and children are not accountable, why did God count children among the wicked and have them killed?
Eze 9:4 And the Lord said to him, “Go throughout the city of Jerusalem and put a mark on the foreheads of those who grieve and lament over all the detestable things that are done in it.” 5 As I listened, he said to the others, “Follow him through the city and kill, without showing pity or compassion. 6 Slaughter old men, young men and maidens, women and children, but do not touch anyone who has the mark.”
Again, this is the bottom line truth:
Acts 4:10 “It is by the name of Jesus Christ of Nazareth, whom you crucified but whom God raised from the dead, that this man stands before you healed. 12 Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved.”
Jn 3:36 “He who believes in the Son has eternal life; but he who does not obey the Son shall not see life, but the wrath of God abides on him.”
1 John 4:15 If anyone acknowledges that Jesus is the Son of God, God lives in him and he in God.
So... no age of accountability, but the good news and grace that applies to adults also applies to children: salvation through faith in Jesus Christ.
