There is a clear and simple message about Christian behavior in the verses of the video but there are many more verses that support the main idea. The Bible clearly challenges the readers to manage their behavior.
God understands the problems and issues we face as people living in this crazy world. Many problems can be traced to Satan and his rebellion against everything of God. At the same time we must face the consequences of our own bad decisions. This reality is not hidden in the text of the Bible.
To say we have no role in the future as it unfolds is to deny the picture of reality as we see it in the world around us and the picture of the world we see in the text of the Bible.
It will take effort and determination on our part to make changes in our individual thoughts, words and actions. This may seem like work and some people have a problem with that idea. Christians know that works do not impress God. We Christians put forth effort and determination and work diligently to do what God want us to do out of respect and gratitude to God for what God does for us and in us.
God provides the strength and will to do as He asks. God is a great Helper that is willing and able to assist us. Think of the Helper as the Holy Spirit. According to the Bible the Holy Spirit is a person that comes along side you to guide and help you. The Helper always tells the truth. You can rely on the divine Helper. God has made every provision to ensure your success.
Keep reading and studying. Read, think, reason, understand and ask God for wisdom to navigate through life.
