So the followers brought the boy to Jesus. When the {evil} spirit saw Jesus, the spirit attacked the boy. The boy fell down and rolled on the ground. He was foaming from his mouth. Jesus asked the boy's father, "How long has this been happening to the boy?" The father answered, "Since he was very young. The spirit often throws him into a fire or into water to kill him. If you can do anything for him, please have pity on us and help us." Jesus said to the father, "You said, 'Help him if you can.' All things are possible for the person that believes." The father became very excited. He said, "I do believe. Help me to believe more!" Jesus saw that all the people were running there to see what was happening. So Jesus spoke to the evil spirit. Jesus said, "You evil spirit that makes this boy deaf and stops him from talking—I command you to come out of this boy and never enter him again!" The {evil} spirit screamed. The spirit caused the boy to fall on the ground again, and then the spirit came out. The boy looked like he was dead. Many people said, "He is dead!" But Jesus held the boy's hand and helped him stand. Jesus went into the house. His followers were alone with him there. They said, "We could not force that evil spirit out. Why?" Jesus answered, "That kind of spirit can only be forced out by using prayer." —Mark 9:20-29 (ERV)

"Not every person that says that I am his Lord will enter the kingdom of heaven. The only people that will enter the kingdom of heaven are those people that do the things that my Father in heaven wants. —Matthew 7:21 (ERV)

I mean that you are saved by grace. And you got that grace by believing. You did not save yourselves. It was a gift from God. No! You are not saved by the things you have done. So no person can boast {that he saved himself}. God has made us what we are. In Christ Jesus, God made us new people so that we would do good things. God had already planned those good things for us. God had planned for us to live our lives doing those good things. —Ephesians 2:8-10 (ERV)
