I'm feeling generous, so here is the one verse you said didn't exist
*** They entered into a covenant to seek the Lord, the God of their fathers, with all their heart and soul; and everyone who would not seek the Lord, the God of Israel, was to be put to death, whether small or great, whether man or woman.* (2 Chronicles 15:12-13 NAB)
Not the sharpest crayon in the box. You were supposed to be looking for verses that support these parents refusal to accept medical treatment....... or is that why you wanted to change the topic. And christians have the new testament.
Ephesians 2
15by abolishing in his flesh the law with its commandments and regulations.
Hebrews 8
13By calling this covenant "new," he has made the first one obsolete; and what is obsolete and aging will soon disappear.
Romans 10
4Christ is the end of the law so that there may be righteousness for everyone who believes.
Romans 7
6But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code.
2 Corinthians 3
13We are not like Moses, who would put a veil over his face to keep the Israelites from gazing at it while the radiance was fading away. 14But their minds were made dull, for to this day the same veil remains when the old covenant is read. It has not been removed, because only in Christ is it taken away.Galatians 3
13Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: "Cursed is everyone who is hung on a tree."
23Before this faith came, we were held prisoners by the law, locked up until faith should be revealed. 24So the law was put in charge to lead us to Christ[h] that we might be justified by faith. 25Now that faith has come, we are no longer under the supervision of the law.
