I believe in one true God who is almighty, omnipresent and all knowing. Able to do anything in accordance to his will, he is Father, Son and Holy Spirit.
It is by mercy and grace alone that we are saved, which is effectuated by Jesus' crucifixion, burial and resurrection and that by faith we accept that free gift given to us undeservingly.
Choosing Christ is not a matter of intellect but rather a matter of the heart, if we go into something with presuppositions we won't ever find the truth wherever it leads us, instead if we chose to follow the evidence and clear trace God left for us it will always aim back to him.

John 3:16 (NIV)
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
