-Do not worship other Gods or idols, graven images or take his name in vain & Set aside a day of rest for God for worship
I agree no one who loves God will do any of the following and they do set aside a day or worship.
-Dont lie, steal, kill, covet, commit adultery, disrespect your parents. & Dont commit Sexual Immorality, Lev 18, 1 Cor 6:9-11, Gal 5, Rev 21
Lets look at the rest since many many believers have confessed with their mouth Jesus is Lord and believe in their heart and they are saved yet:
-It has been proven that 70-80% of believers engage in premarital sex
-Many believers are shacking up
-Many believers get drunk all the time
-Many believers curse and curse others out in a finger snap when they are upset.
-Adultery is a problem among believers too and constant remarrying as well.
-Pornography is a huge problem that close 50% of believers view porn.
- I wont even go into detail with all the coveting and disrespect of parents by Christians.
-Stealing by prosperity Gospel preachers extorting members into giving them all their money or else they are robbing God.
-Bible say to obey the laws of the land, yet most Christians have no regards to road rules and drive 20+ over the speed limit just like the rest of the world.
-Dont steal, but many Christians download illegal copies of software, music, and movies just like the rest of the world
Yet like you said, no one would Love God and their Neignbor and do any of what I listed above, but yet its rapant among Christians right now.
