How would you understand a new complicated washing machine with lots of
buttons, settings and programmes?
You would read the manual.
Life is complicated, so we need a manual. Christians believe that the Bible is
God's Word, given to us, and it is the manual for life.
The Bible teaches that there is one God, who existed before creation. God is
present in three "forms", the Father, Son (Jesus) and Holy Spirit, referred to as
the Trinity. Like water, which exists as ice, steam and liquid water - all very
different, but all are the same H2O.
1 Corinthians 8:6 "yet for us there is but one God, the Father, from whom all
things came and for whom we live; and there is but one Lord, Jesus Christ,
through whom all things came and through whom we live."
John 1:3 "Through him [Jesus] all things were made; without him nothing was
made that has been made."
