If there is anything good that happens in life it's from Jesus.

John 10:9-11 (New International Version, ©2011)


9 I am the gate; whoever enters through me will be saved.[a] They will come in and go out, and find pasture. 10 The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full.

11 “I am the good shepherd. The good shepherd lays down his life for the sheep.

Let's rememebr that when bad things happen, and they do. Things that are not just dumb mistakes or causes of entropy, but things that are willfully done for evil come from Satan. The Bible points out that the thief (Satans) work is to steal kill and destroy. Every instance of these actions involved with the human race is a result of the work of the Devil, or enemy if you are in the Kingdom of God. This is his work he is constantly looking to destroy good.

1 Peter 5:8 (New International Version, ©2011)says,

8 Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour.

We often cannot understand how a person can do evil as it seems to not be in us (remember it isnt in you if you are a new creation). Those who are not new creations, however, are described as we once we, in Romans 3:9-11 (New International Version, ©2011)

No One Is Righteous
9 What shall we conclude then? Do we have any advantage? Not at all! For we have already made the charge that Jews and Gentiles alike are all under the power of sin. 10 As it is written:
“There is no one righteous, not even one;
11 there is no one who understands;
there is no one who seeks God.

Dispite what secular humanism would teach us, there is no good in everyone. The potential people have to to become good, through the new birth in the belief in Jesus Christ.

C.S. Lewis says, ""[Pain] removes the veil; it plants the flag of truth within the fortress of a rebel soul." --The Problem of Pain

When we see the works of the enemy (Satan), whether it is violence, pride, vanity, self worship, or anything that takes glory from God and brings evil to his creation we can see the enemy for who he really is. Do not see that God is causing some trouble for you to learn from, it is not God. It says in James 1:16-18 (New International Version, ©2011)

16 Don’t be deceived, my dear brothers and sisters. 17 Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows. 18 He chose to give us birth through the word of truth, that we might be a kind of firstfruits of all he created.

If it is good it is from God. If it is evil it is from the enemy of your soul, your body, and your spirit. The son in the Kingdom of God can find comfort here:
1 John 5:3-5 (New International Version, ©2011)
3 In fact, this is love for God: to keep his commands. And his commands are not burdensome, 4 for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith. 5 Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God.
