Romans 2:6-8, 13

who will render to every man according to his works: to them that by patience in well-doing seek for glory and honor and incorruption, eternal life: but unto them that are factious, and obey not the truth, but obey unrighteousness, shall be wrath and indignation

for not the hearers of the law are just before God, but the doers of the law shall be justified
