Our salvation, according to the history in the Bible, depends on our willingness to obey God's commandments. In Genesis we read that Adam and Eve lost eternal life because they were disobedient to God when they ate the fruit of a tree that God had told them not to eat. God gave them no second chance.
In John 14:15 Jesus said, “If you love me, obey my commandments." This means that if we don't follow what He had told us to do or not to do, we don't love Him. And He wants nothing to do with Lucifer, Adam and Eve, and the millions of people who drowned during the big flood in Noah's time who don't love Him. They refused to obey His commandments. They see God's commandments as an additional burden that they have to carry in their lives. History tells us that obedience to God is mandatory. It is a requirement that God will not bargain with us. We saw this in the history of Adam and Eve. We also saw what happened to the millions of people who were destroyed during the big flood because they refused to obey to God's commandments that Noah had presented to them.
A common definition of obedience is “dutiful or submissive compliance to the commands of one in authority.” God is the Authority figure. His commands are given in the Ten Commandments, and in other parts of the Bible.
The Ten Commandments consist of two parts. The first part describes our duties toward God. The second part describes our duties toward our neighbors and fellow human beings. Did God invalidate any part of the Ten Commandments? The answer is no! Jesus said, "Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill. For I tell you truly, until heaven and earth pass away, not a single jot, not a stroke of a pen, will disappear from the Law until everything is accomplished.…" Matthew 5:17,18. Nothing invalidates the Law, not even faith in Christ.
In Romans 3:31 the apostle Paul wrote, "Do we, then, nullify the Law by this faith? Certainly not! Instead, we uphold the Law." God did not invalidate the Ten Commandments. His Law last forever. It has no expiration date.
Some Christians claim that obedience to the Ten Commandments is no longer relevant or valid because salvation is based on their personal relationship with God. They believe that "everything is nailed to the cross when Jesus died." If that is true, can Christians worship images of God? Can Christians steal, murder, or commit adultery as long as they have a "good" personal relationship with God? Obviously they cannot without committing sin. Others argue that believe in Christ is the determining factor in our salvation. Really? Don't the demons also believe in Christ? Still others insist that they live under "grace" and that grace will cover their transgressions of the Law. Does God discriminate Adam and Eve and the millions of people during the big flood and destroy them all, but give these Christians special treatment - plenty of grace for violating God's commandments? No, it doesn't make any sense.
Is God in the New Testament a different God than Moses' God described in the Old Testament? I don't think so. There is only ONE God, not two or three. "Jesus Christ is the same yesterday and today and forever." Hebrews 13:8
"God is not human, that he should lie, not a human being, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill?" Numbers 23:19. We also know what the Scripture says in Matthew 24:24, "For false christs and false prophets will rise and show great signs and wonders to deceive, if possible even the elect." The Bible says that God is not a human being. He doesn't change His mind from the Old Testament to the New Testament. He is the same yesterday and today and forever!
Who change? It must be humans, because God doesn't change His mind! They are humans who are more interested in making a name for themselves. Be careful! 1 Thessalonians 5:20-21 says, "Do not despise prophecies, but test everything; hold fast what is good."
What is the standard that we must always use to test everything? I believe that the best way to test everything is to test our logic against God's logic. Test your preacher's logic against the Scripture's logic. Test everything against the logic of God's words in the Bible. Why? Because the Scripture says, repeat, "For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect." Matthew 24:24. I also believe that one of the critical prerequisites in order to be able to "test everything" is that we must be capable of reasoning correctly and use our God-given logic. An important reason why Adam and Eve failed to obey God was that they did not use the logic that God had taught them. Instead, they followed the serpent's or Satan's logic.
