Generally I like to point to the Apostles Creed as a statement of faith.
I believe in God, the Father Almighty,
the Maker of heaven and earth,
and in Jesus Christ, His only Son, our Lord:
Who was conceived by the Holy Ghost,
born of the virgin Mary,
suffered under Pontius Pilate,
was crucified, dead, and buried;
He descended into hell.
The third day He arose again from the dead;
He ascended into heaven,
and sitteth on the right hand of God the Father Almighty;
from thence he shall come to judge the quick and the dead.
I believe in the Holy Ghost;
the holy catholic church;
the communion of saints;
the forgiveness of sins;
the resurrection of the body;
and the life everlasting.
I like this creed because it is accepted by the larger Christian church. It dates back to the first century in various forms and gives a nice basic statement of the Christian faith.
J.I. Packer wrote a helpful book on this creed.
For a further definition I like the one from Ransomed Heart Ministries listed below:
We believe the Bible to be the inspired, only, infallible, inerrant, authoritative Word of God.
We believe in the One True God, the Sovereign, eternal Creator of all that exists, both seen and unseen. God is eternally existent in three persons, yet one God: Father, Son, and Holy Spirit.
We believe in the deity of our Lord Jesus Christ, in His virgin birth, in His sinless life, in His miracles, in His vicarious and atoning death through His shed blood, in His bodily resurrection, in His ascension to the right hand of the Father, and in His personal return in power and glory.
We believe God created mankind in His image. Adam and Eve, the first human beings, chose to rebel against God and go their own way. As a result, all of mankind became separated from God; the image of God in man was distorted; mankind became subject to the power of the devil; and the sinful nature was passed on to all their progeny. Because of original sin, unregenerate human beings are incapable of pleasing or commending themselves to God. The only remedy for mankind's pitiful predicament is redemption through faith in Jesus Christ.
We believe that when a person exercises saving faith in Christ he passes, immediately, out of spiritual death into spiritual life and from the old creation into the new, a new nature and a new heart imparted; being justified freely by grace, he is accepted before the Father as Christ, His Son, is accepted and loved as Christ is loved, having his place and portion linked to Christ and one with Christ—forever.
We believe in the present ministry of the Holy Spirit by whose indwelling the Christian is enabled to live a godly life.
We believe in the resurrection of both the saved and the lost—they who are saved unto the resurrection of life and they who are lost unto the resurrection of damnation.
We believe in the spiritual unity of believers in our Lord Jesus Christ.
