The Bible sadly can be interpreted in many ways depending on the person who wants to make a point to prove they are right.
If we pick and chose certain verses and leave others out we can make it say lots of things God is not.
If we take the Gospels which are the recollections of the time Jesus was alive on earth he gives us some very clear messages
To love one another and not judge
To treat the poor with respect and be careful how we use our money
The importance of God, Father Sin and Holy Spirit
He never mentions sexuality other than people who are not faithful in marriage

My dad went on one a year ago, it helped him understand the Holy Spirit and he is still not a raving evangelical (!) but has agreed to help on the next course. I did a course over 20 years ago and it helped me understand who Jesus is.

One of my favourite verses is
We love because God loved us first
