Now that's a difficult question to answer briefly.  You could go to the Methodist Church national website and look at this hymn Methodist hymn about belief, or you could read the Nicene or Apostles creed (see below) and then you could get in touch to talk about it, or you could just get in touch now if that's easier.

Nicene Creed

We believe in one God, the Father, the Almighty, maker of heaven and earth, of all that is, seen and unseen.

We believe in one Lord, Jesus Christ, the only Son of God, eternally begotten of the Father, God from God, Light from Light, true God from true God, begotten, not made, of one Being with the Father.  Through him all things were made.  For us and for our salvation he came down from heaven: by the power of the Holy Spirit he became incarnate from the Virgin Mary, and was made man.  For our sake he was crucified under Pontius Pilate; he suffered death and was buried.  On the third day he rose again in accordance with the Scriptures; he ascended into heaven and is seated at the right hand of the Father.  He will come again in glory to judge the living and the dead, and his kingdom will have no end.

We believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father.  With the Father and the Son he is worshiped and glorified. He has spoken through the Prophets.  We believe in one holy catholic and apostolic Church.  We acknowledge one baptism for the forgiveness of sins.  We look for the resurrection of the dead, and the life of the world to come.  Amen.

Apostles creed (ecumenical version)

I believe in God, the Father Almighty,
creator of heaven and earth.

I believe in Jesus Christ, his only Son, our Lord,
who was conceived by the Holy Spirit,
born of the Virgin Mary,
suffered under Pontius Pilate,
was crucified, died, and was buried;
he descended to the dead.
On the third day he rose again;
he ascended into heaven,
is seated at the right hand of the Father,
and will come again to judge the living and the dead.

I believe in the Holy Spirit,
the holy catholic church,
the communion of saints,
the forgiveness of sins,
the resurrection of the body,
and the life everlasting. Amen.
