12 God is pleased with people who bravely/patiently endure difficulties. And when, by bravely enduring difficulties, they have proved that they truly trust him, he will give them eternal life. That is the reward [MET] that he has promised to give to those who love him.

13 If people are tempted to do something that is evil, they should not think that it is God who is tempting them, because God is totally/completely good. He never tempts anyone to do what is evil, nor can he ever be tempted to do anything evil. 14 But people strongly desire to do evil [PRS] things, and as a result they are tempted by those desires {those desires stimulate them} to do something evil [PRS, DOU]. 15 Then, because they have desired [MET] to do evil [PRS] things, they begin to [MET] do [PRS] them. And when they have become ones who habitually do what is evil [MET], if they do not turn away from their sinful behavior, they will be separated from God forever.
