I'll see your Psalm 58:3 and raise you one 1 Corinthians 14:20 In regard to evil be infants, but in your thinking be adults.
Paul infers that infants are not associated with evil.
Your view is not comprehensive. Don't you see that? You simply aren't correctly correlating the various scriptures.
Now if he uses your interpretation that infants are grossly sinful, then his statement means the following:
IN REGARD TO EVIL GO OUT AND BE GROSSLY SINFUL.
You have Paul advocating antinomianism, don't you?
What is the correct interpretation of that verse:
a. in regard to evil "be innocent toward it."
or
b. in regard to evil "go out and be grossly sinful."
CHOOSE A or B. Which one do you think is the correct interpretation?
If xzins is correct, and infants don't sin, then wouldn't we be better off slaughtering all the innocent little ones before they sin, thus assuring their salvation?
If xzins is correct, then the most loving thing I could have done for my twin grandsons would have been to kill them at birth. That way, they don't have the oportunity to say "no" to Christ and decide themselves into hell.
However, I know that God has chosen, on the basis of His good pleasure, to save all those who are His. As a result, I can trust in His heart, knowing that He does all things well.
