Our deeds perfect our beliefs. Partiality and wrong thinking often live in the same heart. The fact that we will be judged should affect our thoughts and actions. We reap what we sow. Whenever they hear His name taken in vain, Christians should remember they are named after Jesus.
Works give life to faith.
You cannot demonstrate faith without works. My brethren, have not the faith of our Lord Jesus Christ, the Lord of glory, with respect of persons. But ye have despised the poor. But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors. For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
