How Do Christians Examine Whether or not They Are In the Faith?
2 Corinthians 13:5 Updated American Standard Version (UASV)
5 Keep testing yourselves to see if you are in the faith. Keep examining yourselves! Or do you not realize this about yourselves, that Jesus Christ is in you, unless indeed you fail to meet the test?
Keep Examining Yourselves
The phrase keep examining yourselves is self-explanatory, but it involves a self-examination. We may have been a Christian for a number of years, but how many times have we had a spiritual checkup. Every six months we are to go in for a dental cleaning, and unless there is a problem, we should get a health screening once a year. The problem with our spirituality is it is far more susceptible to injury than we are physically. The author of Hebrews warns us, “We must pay much closer attention to what we have heard, lest we drift away from it.” (2:1) One chapter later, we are told, “Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin.” (3:12-13) This same author warns us about falling away (6:6), becoming sluggish (6:12), and growing weary or fainthearted (12:25).
Why would this be the case? If we are saved, why is it necessary that we keep examining ourselves? Why would we still be susceptible to bad behaviors to the point of drifting away, to the point of having an unbelieving heart, falling away, becoming sluggish, growing weary or fainthearted?
There are four reasons. (1) First and foremost, we have inherited sin, which means that we are missing the mark of perfection. (2) In addition, our environment can condition us into the bad thinking and behavior. (3) We have our human weaknesses, which include inherent tendencies that we naturally lean toward evil, leading us into bad behaviors. (4) Moreover, there is the world of Satan and his demons that caters to these human weaknesses, which also brings us down the path of wrong thinking and behaviors. After our self-examination, what is needed if we are to overcome any bad thinking or behaviors and how are we to avoid developing them in the future? We will offer more on this in each chapter as well as two appendices at the end, but we offer this for now. It is paramount that we fully understand what all is involved in our human imperfection and never believe that we are so strong spiritually that we would never fall away, slow down, or becoming sluggish in our walk with God.
Obviously, this should be of the greatest concern to each one of us. We may be a person of good character and believe that in any situation, we will make the right decisions. However, the moment that innocent appearing situation arises, we are plagued with the inner desire toward wrong. We need to address more than what our friends, or our workmates or our spouse may see. We need to look into our inner self, in the hopes of determining, who we really are, and what do we need to do to have a good heart (i.e., inner person).
As we know, we could not function with half a heart. However, we can function, albeit dysfunctional, with a heart that is divided. Yes, we have things outside of us that can contribute to bad thinking, which id left unchecked will lead to bad behavior, but we also have some things within. The apostle Paul bewailed about himself, “For I do not do the good I want, but the evil I do not want is what I keep on doing. Now if I do what I do not want, it is no longer I who do it, but sin that dwells within me.” (Romans 7:19-20) This is because all of us are mentally bent toward the doing of wrong, instead of the doing of good. (Gen 6:5; 8:21; Rom 5:12; Eph. 4:20-24; Col 3:5-11) Jeremiah the prophet informs us of the condition of our heart (our inner person), “The heart is deceitful above all things and desperately sick; who can understand it?” These factors contribute to our being more vulnerable to the worldly desires and the weak human flesh than we may have thought. One needs to understand just how bad human imperfection is before they can fully implement the right Christian Living Skills.
Returning to the book of Hebrews, we are told, “solid food belongs to the mature, to those who through practice have their discernment trained to distinguish between good and evil.” (5:14) We will have evidence that we are one of the mature ones by training ourselves to distinguish between good and evil. We likely believe that we are already spiritually mature, which may very well be the case. Nevertheless, we are told by Paul to carry out this self-examination and to keep on examining ourselves, to remain that way, and even to improve upon what we currently have by way of maturity. Just as a man or woman in a marathon must continually train their muscles to surpass others in the sport, our discernment (perception) needs to be trained through regularly and rightly applying the Word of God. Throughout this publication, we will apply the inspired words of James, Jesus’ half-brother.
James 1:22-25 Updated American Standard Version (UASV)
22 But be doers of the word, and not hearers only, deceiving yourselves. 23 For if anyone is a hearer of the word and not a doer, he is like a man who looks intently at his natural face in a mirror.
24 for he looks at himself and goes away, and immediately forgets what sort of man he was. 25 But he that looks into the perfect law, the law of liberty, and abides by it, being no hearer who forgets but a doer of a work, he will be blessed in his doing.
When we are inundated in the Word of God, it serves as the voice of God, telling us the way in which to walk.
 Lit the face of his birth
