I would heartily agree with the responses so far, but also I would recommend a couple more easy, couple-of-minute reads of a less 'technical' (for want of a better word) nature. These won't inform you about the role of the church, or about Jesus, or about morality and so on, but I think they are wonderful places to see the glory and appeal of God.
I found Psalms very useful, and it is beautiful poetry on top!
I would recommend Psalm 18 to understand the strength and support of God,
Psalm 22 to understand how God is there even in the hardest of times,
Psalm 23 because it's one of the most beautiful parts of the whole Bible,
Psalm 100 to know that God should be exalted and praised!
Psalm 121 to know that God is always there
Psalms 145 and 147 to praise God more.
These are only a tiny selection of Psalms for their purposes, and I'm sure many could have done a better job than me of recommending some, but see what you think. Think of the beauty of that which these Psalms are directed to (God!).
Other than that, for someone coming to religion from a period away from God, Jonah can deliver a powerful message, especially his speech in Jonah 2. It is worth thinking about this from the point of view of someone who wishes to be returned to God's favour.
I hope this helps.
(I realise that this post technically breaks the rules for this section of the forum as I have not tagged myself as a Christian, but I hope that the content of my post shows that I am merely attempting to lend a helping hand, as opposed to assert any undue non-religious influences on the thread!)
