1:13-15 What do we learn from what James says here?

We learn from this that God does not tempt or test anyone. He does not will ill to people to make them fall.

Temptation is the arousal of man's own evil thoughts and desires which lead him to become trapped in sin when he succumbs to them (CP 2Sam 11:1-27).

Notice the progression of events that led to David's sin here - it is the same as Jas 1:13-15 teaches.

David became trapped in sin by succumbing to his own evil thoughts and desires. He was drawn away of his own lust and enticed, which led to adultery, murder, and then a cover-up. No-one can blame God when they are tempted, because the temptations originate in their own hearts (CP Pr 4:23; Jer 17:9; Mk 7:21-23).

Believers only deceive themselves if they think that it is God testing them. Every sin we commit originates with us - only good things come from God (CP Jas 1:16-17).
