James 2:18 Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works. 19 Thou believest that there is one God; thou doest well: the devils also believe, and tremble. 20 But wilt thou know, O vain man, that faith without works is dead? 21 Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? 22 Seest thou how faith wrought with his works, and by works was faith made perfect? 23 And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God. 24 Ye see then how that by works a man is justified, and not by faith only. 25 Likewise also was not Rahab the harlot justified by works, when she had received the messengers, and had sent them out another way? 26 For as the body without the spirit is dead, so faith without works is dead also.
Our faith is seen by our works or they show what we believe. Belief with no deeds is no higher than what demons believe. I’d call that demon faith. There is something just as bad and it is dead faith. Our works after salvation justify us that the original belief in God we exercised was genuine. That is what the scriptures say of Abraham’s faith when he was willing to offer up his son Isaac. Rahab is also used as one whose works justified her. Both of their works gave evidence, or proof, that their initial experience of belief in God was valid.
To a person destitute of daily food, words alone don’t prove I care though I may say I care a thousand times. Faith like love always produces good works when it is genuine. Faith cannot be shown to be genuine or proven to men to be genuine if not accompanied by good works. If faith is there it will have some practical visible influence on one’s life.
The most certain proof of the existence of faith is good works. It shows without a doubt you are saved for faith always produces evidence of its existence which is good works. Faith without good works is as lifeless as a corpse or a body without a spirit inside. We know the spirit is inside, though you cannot see it, because we see the body alive outside. We can know faith or genuine belief is inside of a person by the good works we see outwardly.
We can know a person believes in tithing, because we see him tithe.
We can know a person believes in prayer, because we see him praying.
We can know a person believes in church, because we see them attending.
We can know a person believes in a church’s vision and mission because we see them working to bring it to pass.
We can know a person believes in the graces and gifts God has given them by seeing them serve and function.
We can know a person believes their body is the temple of the Holy Ghost because we can see them living holy.
“Even so faith, if it hath not works, is dead, being alone James 2:17.” Faith alone saves (Rm. 3:28) but the faith that saves is not alone (James 2:14, 17, 20, 22, 26). It should issue forth good works.
