Here is another one of those things that people have either not been taught correctly or at all. In Romans there is a major section of this letter that deals with the “law” and how those that follow Christ are no longer in need to follow. Many think this means they do not need to follow the Bible at all, others think you do not need to follow the Old Testament, others feel you are free to do as you please as long as they say they are one with Christ.
All of these ideas are false.
What is going on in Romans is an explanation on the need to not give sacrifices at the temple any longer. No longer is the need to prepare food a certain way. No longer necessary is the requirement to follow this ritual or that ritual which have been set forth by the Pharisees. One of the main reasons for this is by the time that Christ walked the earth many un-needed things had been added by humans and not God. So in actuality the original law was not even being truly followed as Christ Himself point out but a type of man-made legalism.
Now what is important Jesus clearly said He came to fully the law and not replace it. So this means that sacrifices were not necessary due to Him going to the cross and being beaten, bleeding as well as dying for us upon it. This very act states that there was, is and will be sin that only His blood can wash away, but due to free-will those that ask Christ into their life’s must repent of their sin.
Now here is the key word: “repent” which means to turn away from. In other words stop doing. If you ask God into your life and you continue to live in sin and do nothing to end nor feel any need to stop sinning. Then per the Bible itself those that continue to be of the world, which sin is a part of, then they choose the world over God and are not even welcome in heaven.
Let’s allow that to sink in a moment.

In several passages within the Bible it is made clear that it is either, or, not both. It is either sin or God, it is either the world and those things of the world or God. It is either do as the Bible says and accept all that the Bible says, which includes what is and what is not a sin, or do whatever makes you happy.
It clearly states within the Bible that for those that choose God their life will not be an easy life. There will be pain suffering and sometimes as is now happening in the Middle East things much worse. Torture, beheading, crucifixions and other terrible things. This what you signed onto when you accepted Jesus.
If any promise you riches and happiness in this world they are of this world not God’s world and you should leave them to their happiness. For they have chosen their rewards here upon this earth in this life that will last nearly one hundred years. Those that truly follow Christ are promised their rewards in the eternal life, a life that will last billions of years, which sounds more interesting? My answer? The eternal life.
