What is a Christian? - How Can a Person Be Sure?

How Can a Person Be Sure?

Several things assure the Christian that he or she is a real Christian. Firstly, God's promises about forgiving them and receiving them are true and can be relied on.
Secondly, their changed attitudes toward God, sin and the world assure them that God has made them new people. When God does this it is forever. (John 6:37-44) Thirdly, there are times when Christians feel the wonder of God being their Father. St Paul tells us that this is the Holy Spirit bearing witness with our spirit that we are God's children. (Romans 8:15-16) A person knows he or she is a Christian because they do not want to go on in sin any more. They have a new love for all people. All of these are gifts from God.

"He said to them, 'Go into all the world and preach the good news to all creation.' "

Mark 16:15
