Atheists have no other gods before God, ergo they have maintained the first commandment.
Further, atheists don’t hate their parents or children by instruction yet Jesus commands that. Atheists keep the commandments. Jesus’ instruction does not meet with that commandment or his ‘Love Thy Neighbour’ law. Which do you follow?
Exodus 20 12
Honour thy father and thy mother: that thy days may be long upon the land which the Lord thy God giveth thee.
Luke 14 26
If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
