Jesus is not suggesting that God will tempt us to evil if we do not petition Him otherwise. James 1:13 specifically says that God tempts no one. God may test, but He never tempts to evil. A test is for growth; temptation is toward evil. Not all temptation is from Satan, for James also says that we are tempted by our own lust. The evil inherent within the heart of man is capable of tempting man without Satan’s help.
