Summarize this article:

The first commandment in the Bible states that “You shall have no other gods before me.” Christianity is a monotheistic religion, which means that you can only worship one God, the Father. God is the Father of Jesus, and according to the Bible, He created the universe and preserves all things. The Bible explains that God appears in many forms and has power beyond what any human could understand. Believing in the power of a singular God’s is one of the most important parts of Christianity. Read the story of the original sin, which is the first story in the Book of Genesis, and then read the many stories of the life of Jesus in the Gospels. According to these accounts, God sent his only Son, Jesus, to the world so that he could suffer and die on the cross to absolve humanity of original sin.  The general plot of this story is that Adam and Eve succumb to temptation and commit “original sin” in the Garden of Eden, which guarantees that all humans will be born having sinned. This means that they would not have been able to get into heaven without Jesus’ death and acceptance into heaven. The Book of Romans states that “God demonstrates his own love for us in this: While we were still sinners, Christ died for us." Know that in the Bible, God is made of 3 parts, including the human form of Jesus, and the metaphysical form of the Holy Spirit, which are considered the Holy Trinity. Like a triangle, which must have 3 sides to exist, God is all 3 parts of the Trinity at once, and he uses the various “sides” of Himself to accomplish His goals. The Book of John explains that “For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.” In this quote, Jesus is considered “the Word” because he came to Earth to spread the word of God. When a Christian person dies on Earth, they are welcomed into Heaven for an eternal afterlife at the hand of God. Read about this in Romans, which states "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord." While no one is sure what this afterlife looks like, recognize that spiritual experiences on Earth can help you understand it more. If you have questions about the afterlife, talk to a pastor or spiritual guide about your concerns or thoughts. This can help you lead a life that will ensure your acceptance into Heaven. Be confident that your belief in Jesus as the Son of God guarantees that you can have a personal relationship with God. Know that God accepts and forgives you because you believe that Jesus suffered and died on the cross for your salvation.  This concept is known as the “justification of faith,” and serves as the foundation for a positive relationship with God that allows for personal growth and understanding. In Proverbs, the Bible states that followers should “Trust in the Lord with all your heart, and do not lean on your own understanding.” This encourages Christians to believe that their relationship with God is strong and that He will guide them, even if they don’t understand His power.

Summary:
Believe that there is one God, the Father. Recognize Jesus as the Son of God, sent to save humanity from original sin. Acknowledge the Holy Trinity as the Father, Son, and Holy Spirit. Conclude that there is life after earthly death. Trust that your beliefs will lead to a strong relationship with God.
