The biggest obstacle to faith for a lot of people is this: “If God is all powerful, then why does He cause (or allow) bad things to happen?”

There's something fundamental that we must establish before we ever address this question directly: God is good, all the time (James 1:16-17).  

We know this, at least in part, by what Jesus did. Jesus said that he who has seen him has seen the Father (John 14:8-9), and Jesus went about doing good, and healing all that were oppressed of the devil (Acts 10:38, Matt 15:30, Matt 4:23-24, Matt 8:16, Matt 9:35, Matt 10:1, Matt 12:15, Matt 15:30, Luke 4:40, Luke 10:9).  He never refused healing to anyone who came to Him. He never harmed anyone "for their own good," or put a disease on anyone "to teach them something" or "to discipline them." Not once. In fact, He actively worked against all sickness and disease, to destroy the devil's work (1 John 3:8). He is the same today as He was when He was on earth (Hebrews 13:8).

God the Father doesn't change either (Malachi 3:6). We know of God's character from His names in the Old Testament. He is Jehovah Nissi (The Lord my Banner - Ex 17:15). He is Jehovah-Raah (The Lord my Shepherd, or My Friend - Gen 48:15, Psalm 23:1, 80:1, Ez 34:11-15). He is Jehovah Rapha (The Lord That Heals, Ex 15:26). He is Jehovah Shammah (The Lord is There - He has not abandoned you: Eze 48:35). He is Jehovah Tsidkenu (The Lord Our Righteousness, Jer 23:6, 33:16). He is Jehovah Mekoddishkem (The Lord who Sanctifies You: Ex 31:13, Lev 20:8). He is Jehovah Jireh (The Lord will Provide, Gen 22:14). He is Jehovah Shalom (The Lord is Peace, Judges 6:24). He is Jehovah Sabaoth (The Lord of Hosts, 1 Sam 1:3, Ps 24:9-10, 84:3, Isa 6:5).

Many other scriptures establish His goodness. He is ONLY good. (1 John 1:5, Psalm 84:11-12; Psalm 146:6-10; Psalm 107:9, Psalm 31:19, 1 Tim 4:4-5, Eph 1:3, Romans 8:28, Ps 103:2-5, Ps 145:16-19).

God doesn’t do bad things to His children. Yet He’s powerful enough that for those who trust in Him, He can take even terrible circumstances that were not part of His plan, and bring good out of them.“And we know that in all things God works for the good of those who love him, who have been called according to his purpose” (Romans 8:28).

Those who know their scriptures well may point out Old Testament passages that sound like God, in fact, did do evil things. One example is in 2 Sam 24:1, when it says the Lord moved David (in pride) to count the number of his subjects... and then condemned David's sin in having done so (2 Sam 24:10) and punished him severely for it. Yet the exact same story appears in 1 Chron 21:1, where it says Satan moved David to number Israel. This is a very rare glimpse into what was happening in the spiritual realm in the Old Testament, where there is almost no doctrine of Satan. The primary exception to this is at the beginning of the book of Job; otherwise Satan is only mentioned by name here, and in Zechariah 3:1-2. (He is mentioned in Genesis 3 as "the serpent," of course, and also as Lucifer in Isaiah 14:12 and Ezekiel 28 as well.) The Old Testament had almost no doctrine of Satan because the people had no authority over him under the Mosaic covenant. What good would it do to learn that you have a bloodthirsty enemy, but there is nothing you can do to protect yourself from him? Because of this, in the Old Testament, anything supernatural, good or bad, was attributed to God, whether God was the instigator or not. The New Testament (and the revelation in Job 1:6-12) shows that this is not the case; there is a spiritual war going on, and we have an adversary who hates us. (For more on how God's dealings with man changed with different covenants, see my Blood Covenant biblical retellings duology: Blood Covenant Origins and Blood Covenant Fulfilled.)

So if God doesn't cause bad things to happen, why do they happen? Evil comes about as a result of one of or a combination of three things --

1) Satan, the enemy of God and therefore of us, who would like nothing better than to see us destroyed:“The thief comes only to steal and kill and destroy; I [Jesus] have come that they may have life, and have it to the full” (John 10:10).1 Peter 5:8 — “Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour.”

2) A fallen world that will be redeemed one day, but isn’t yet: “For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope that the creation itself will be liberated from
