Perfect Hearts
God in the beginning created human beings and made them subject to their own free choice.
Remember how Pharaoh of Egypt was so obstinate continually going back on his word, loving lying to God to get each plague to quit? Bibles say the true God let his heart be obstinate. Those that love a lie have no place with the true God's Laws because these are truth and love and we must worship God who is love in truth.
What letting the heart be obstinate means is the true God did not perform a miracle to correct Pharaoh's corrupted heart mutated by sin in his blood as a foetus. This miracle would have been against Pharaoh's will. We possess free will to decide as we please. Pharaoh would have needed to ask for the true God to correct his defective heart of his own free will. Guess what, the true God would have made that provision. After all He corrected Nebuchadnez'zar of his arrogant heart that became grossly corrupted over time. Solomon's heart could have been corrected too. Solomon would have needed to ask. Asking is the key. Since Jesus ministry, asking means prayer to the true God in Jesus' name with specific reference to our heart. Yes, you must name the component of your anatomy explicitly.
Even an individual with a heart born corrupted from sin in the blood can be an outstanding faithful servant of the true God, following the Lamb everywhere. This last remaining remnant will be the instrument in government to wipe out Babylon, the great harlot -- Satan. Regardless of congenital heart defect or not, the heart is a treacherous organism because it is filled will sin. Really. It is that simple. This means that when Satan wants to move people in some profane direction all she does is get us to give into the desires of our heart.
The true God communicates with us through our mind and kidneys. The kidneys filter out impurities in the blood. The reason the Psalmist spoke of kidneys is because a relationship with the true God is our kidney against living the sin in our blood. The brain is protected by a blood-brain barrier limiting sin's access to brain tissues.
That said, teach your children the specific anatomic language of their genitals in their native language. Without that they have no way of telling you they are being victimised. There are child development white papers on this subject. You child, of the true God, at any age must use the language of your genitals to explain your challenges. The slang terms of ignorance are an abomination against the true God's perfect human creation, and you want to be perfect if you are sheep of the true God. (God says, "While this message will not self-destruct, goats can ignore it.")
