Some verses from the bible showing God is good.

I Chronicles 16:34
O give thanks to the LORD, for He is good;
For His lovingkindness is everlasting.

Psalm 118:29 Give thanks to the LORD, for He is good;
For His lovingkindness is everlasting.

Psalm 136:1
Give thanks to the LORD, for He is good,
For His lovingkindness is everlasting.

(seeing a recurring theme here...)

Psalm 145:8-9
The LORD is gracious and merciful;
Slow to anger and great in lovingkindness.
The LORD is good to all,
And His mercies are over all His works.

Matthew 19:17
"Jesus is speaking of his Father"
And He said to him, "Why are you asking Me about what is good? There is only One who is good; but if you wish to enter into life, keep the commandments."

I John 1:5
This is the message we have heard from Him and announce to you, that God is Light, and in Him there is no darkness at all.

Habakkuk 1:13
Your eyes are too pure to approve evil,
And You can not look on wickedness with favor.
Why do You look with favor
On those who deal treacherously?
Why are You silent when the wicked swallow up
Those more righteous than they?

Matthew 5:48
"Therefore you are to be perfect, as your heavenly Father is perfect.

The bible doesn't seem to be unclear at all, regarding the goodness of God, and that he is not evil. There are some passages some use to show that God claims to be evil himself, or create evil. This at best, would show a possible "contradiction" in the bible, but does not show god to be evil. When you look at what God has done for us, what he offers each of us, even though we were dead in our sins and slaves to sin, he is absolutely good. How else can he forgive us our sins, and why would he want to do so? It is obviously love, as evil would look nothing like that.

So, when posed with verses that seem to contradict, we must ask ourselves what makes the most sense here, and decide. Many atheists I know, choose to use these verses as proof why the biblical christian god could only be evil. Others when they see the above verses, have to decide if the verses about evil give good reason to negate all the rest of what scripture offers us.

The I John 1:5 passage, in the greek it reads...
"And darkness there is not in him, not in any way." John could not have said it more forcefully.

Those are my thoughts on that, and we all have to decide, and do. :)
