Public schools need God
The God who made everything out of nothing (Genesis 1:2) also wrote on stone tablets the Ten Commandments and gave them to Moses on Mount Sinai (Exodus 20:1-17). They are God's will for the spiritual and moral conduct of man, crated in God's own image (Genesis 1:27).
God wrote these commandments because He knew man needed some guidelines to avoid sinful relations with others. The Bible says that man's heart is deceitful above all things and desperately wicked (Jeremiah 17:9).
Our public schools, pressured by atheists and humanists in the Department of Education, decided God should be expelled, and the Ten Commandments were not to be seen and students could not pray. Not long after that, violence began to occur more often in public schools and on the streets.
Then, when tragedies occur, as happened at Sandy Hook School, the atheists and humanists blame everything and everybody else for causing it. It resulted with the removal of the loving God's protection and blessing on our precious children attending public schools. Satan and his demons then took over and violence has definitely increased.
"You shall not commit murder" is the Commandment of God against murder of any kind: abortion of helpless, innocent babies still in their mother's womb or the shooting of helpless, innocent little children in public schools. It is sin, and God has sentenced all murderers and others to the lake of fire and brimstone forever (Revelations 21:8).
If anyone who would kill human life had seen the Ten Commandments in their school and had known that murder is a punishable sin, they might have thought twice before committing their evil, horrible crime. That is the only prevention that will work.
If America can't trust God in our public schools, again, Satan's crimes will only continue.
