The principles of God, righteousness, and obedience to God's instruction is our savior and protection. Any outward instruction, "do not steal," "do not murder," is based on inward principles, "love others."
This is why it is written:
Romans 13:10 Love does no harm to a neighbor. Therefore love is the fulfillment of the law.
Galatians 5:14 For the entire law is fulfilled in keeping this one command: “Love your neighbor as yourself.”
James 2:8 If you really keep the royal law found in Scripture, “Love your neighbor as yourself,” you are doing right.
We are to guard ourselves to ensure God's message is correct from teachers.
Matthew 16:6 “Be careful,” Jesus said to them. “Be on your guard against the yeast of the Pharisees and Sadducees.”
Matthew 16:11 How is it you don’t understand that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees.”
Matthew 16:12 Then they understood that he was not telling them to guard against the yeast used in bread, but against the teaching of the Pharisees and Sadducees.
2 Peter 2 False Teachers and Their Destruction
2 But there were also false prophets among the people, just as there will be false teachers among you. They will secretly introduce destructive heresies, even denying the sovereign Lord who bought them—bringing swift destruction on themselves. 2 Many will follow their depraved conduct and will bring the way of truth into disrepute. 3 In their greed these teachers will exploit you with fabricated stories. Their condemnation has long been hanging over them, and their destruction has not been sleeping.
4 For if God did not spare angels when they sinned, but sent them to hell,[a] putting them in chains of darkness[b] to be held for judgment; 5 if he did not spare the ancient world when he brought the flood on its ungodly people, but protected Noah, a preacher of righteousness, and seven others;
My prayer is not that you take them out of the world but that you protect them from the evil one.

6 Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
