I was working on a different question and I found that I couldn't actually find anywhere that shows that God actually tests us.
Psalms 26:2 (NIV)
Test me, LORD, and try me, examine my heart and my mind;
Clearly, asking for tests is acceptable, per the Psalm above. Also, it seems that God allows us to be tested:
Job 1:12 (NIV)
The LORD said to Satan, “Very well, then, everything he has is in your power, but on the man himself do not lay a finger.” Then Satan went out from the presence of the LORD.
Another verse that shows that God allows temptation:
1 Corinthians 10:13 (NIV)
No temptation has overtaken you except what is common to mankind. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can endure it.
Does God ever intentionally put things in our way himself to allow us to be tested (as the Psalms says)? Or does God merely allow Satan to give us trials and temptations?
Also, what does the mainstream Protestant doctrines say towards this end?
I'd really like Biblical support for any answer, please.
