God exists as the creator and author of the universe. He has eternally existed in three persons: The Father, The Son, and The Holy Spirit. They are three co-equal parts of one God.
Jesus exists as the Son of God and as co-equal with God. He is fully God and fully man. Born of the Holy Spirit and the virgin Mary, he lived a sinless life giving his all to serving and loving God and humankind. His love went so far as to sacrifice himself on the cross for the sins of all people. He rose from the grave three days later, demonstrating his power over sin and death. He ascended to heaven and will return one day soon to establish his kingdom.
The Holy Spirit exists as God's active presence in the lives of people; living as a relatable presence and an active power in the lives of Christians from the moment of salvation. He lives in this world to make humankind aware of their need for Jesus and guide us towards daily living more like him.
The Bible in it's entirety is inspired by God and given to humankind through the supernatural guidance of the Holy Spirit. It is christians' truth and GPS for their beliefs and life.
Humanity was made in the image of God and designed with the purpose of having a relationship with God. Through an act of disobediance humankind fell into the trap of sin resulting in the alienation of humans from God. While we can do nothing in our own efforts to regain a relationship with Him, the atoning acts of Jesus give us a second chance.
Salvation is God's gift to humankind if we choose to accept it. No amount of good deeds will make up for our sins. It is only through trust and faith in Jesus that we can hope for eternal life in heaven. It all starts with the accepting of Jesus into our life.
Humankind was made to last forever in relationship with God. However, as a result of sin we now have a choice: forever separated from God because of our sin, or forever united with Him because of His love and forgiveness. When we die in this world, we start our eternity in either heaven or hell.
