Christianity

Holy Trinity
The Holy Trinity is an important part of Christian doctrine that states that there is only one God, but that God can be divided into three divine individuals: The Father, The Son and the Holy Spirit. 

The Virgin Birth
Without the Virgin Birth, Jesus would be just another man. However, his name was Immanuel - God with us. For him to be God in human form, He would need a supernatural birth.

 

Jesus was Crucified
Arguably the key element to Christianity is the death of Jesus Christ at the Cross. God sent his only Son, to die sinless at the cross, for all of us sinners. Christ shed his blood for our sake. 

Christ Resurrected
At the Resurrection, Jesus conquers death, and proves once and for all, He is the Son of God.

 

The Second Coming
Jesus Christ will return to Earth to save the believers and cast judgement on the nonbelievers. This will be the final days of mankind. 

Salvation
Jesus Christ was the perfect lamb, the perfect sacrifice. Through Christ, anyone can have salvation. All you have to do is ask.
