God doesn't tempt anyone! In the Lords' Prayer we find an obvious mistranslation, when we read: "Lead us not into temptation, but deliver us from evil". But God knew that this mistranslation would occur, so he inspired James, one of the Apostles, to rectify this faulty doctrine:

13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:

14 But every man is tempted, when he is drawn away of his own lust, and enticed. (James 1:13-14)

In the Lords' Prayer it should have read: "Suffer me not to be lead into temptation".

Safety-valve on temptations. God will not allow that we are tempted above our ability to withstand the temptation. Ever!

13 There hath no temptation taken you but such as is common to man: but God [is] faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear [it]. (1 Corinthians 10:13)

Inactivation of the safety-valve. Now, this promise is only good as long as we don't seek out temptations willfully. God will not fight us to stop temptations, if temptation is what we want! Remember David. He happened to see a woman taking a bath. If he would have turned away, never looking again, the temptation would have died out. But as he chose the temptation, and kept looking, the spirit of prayer left him. "But deliver us from evil" is hard to really feel for a man who is looking with burning pulse. Remember Joseph. He ran, leaving the seductress standing with his garment in her hand. He did not commit adultery and manslaughter, which David did.
