To add to this good post above; ...
ROMANS.7:12 says that God's Law is good for His people. But most Gentiles lead lawless lives, wrt God's Law or Moses Law. So, at ACTS.15:24-29, God only requires new Gentile Christians to begin their born-again lives of the Spirit by keeping 4 simple and non-burdensome laws of Moses.(cf; 1CORINTHIANS.3:1-3) Thereafter, they should slowly learn to keep as many non-burdensome laws of Moses as possible. This is for their own good.
... IOW, God has exempted new Gentile Christians from any law of Moses which is a burden, eg circumcision and kosher foods. They are not exempted from any law which is not a burden, esp morality laws, eg the Ten Commandments(EXODUS.20), DEUT.18:9-14, LEV.10:9 & 18:22, etc.
In comparison, new Jewish Christians are required by God to continue to keep Moses Law, as many laws as possible, because it is not a burden to them.
Those "Christians" who wantonly or ignorantly commit sins/evil-deeds/law-breaking by breaking Moses Law risk losing their salvation while suffering horribly for their sins, eg by cursing/blaspheming God/Jesus and die, like the wife of Job.(JOB.2:8) Be warned by DEUT.28:15, JOB, 1COR.5:5 & 11:30, 1JOHN.5:16-19, HEBREWS.10:26-31, 1COR.6:9-11, REV.22:12-15, ie sins/evil-deeds/law-breaking have consequences - some may lead to a horrible early death(= risk losing salvation/faith) and some may not, eg convicted murderers are usually executed and traffic offenders only have to pay a fine.
Being saved from hell after death rests solely on faith/trust/belief in Jesus as the Christ/Messiah/Savior on the Cross.(JOHN.3:16, GALATIANS.2:16, eg LUKE.23:43, ROMANS.5:12)
The perfect Christians are those who keep God's Law, either partially or fully, and believe in Jesus Christ = gain a good and long life on earth, and be saved from hell(= go to heaven) when they die.(cf; MATTHEW.19:23)
