What Is Christianity?
Christianity is a belief system that centers around the person of Jesus Christ and his sacrifice on our behalf. It is different from other religions in that Christians cultivate a relationship with God instead of following religious rules or practices.
Christian belief explains that people who receive Christ as their Savior will spend eternity in heaven with God. They also believe that the Holy Spirit dwells in them and daily conforms them to the image and likeness of Jesus.
The Bible teaches that sin results in death and that only Jesus can provide salvation to those who will trust in Him. When people become followers of Jesus, they are baptized into His Church and receive the gift of the Holy Spirit.
Unless the Lord returns, all who are alive today will die physically. This includes both physical illness and deaths from other causes.
If Christians have demon problems, then the first thing they should do is ask for prayer and seek out the Lord. If they have a strong faith and a boldness to do this, then they can be effective in casting out those demons and healing the sick.
Many books on deliverance will discuss these issues in great detail. This can be because it is very important for Christians to be able to identify a spiritual problem before they begin to work on it. This is because if you do not identify the source of the problem, then it will continue to grow and destroy your life.
