For it is God who works in you both to will and to do for His good pleasure.
Human nature, because of sin, does not allow our deeds to be good. From our childhood we tend to be selfish and manipulative. Nobody teaches us to be like that, it’s something that comes in our genes. If something good we want and do, it does not automatically come from ourselves, but it is as Philippians 2:13 says: for it is God who works in you both to will and to do for His good pleasure. It is, therefore, God the author of all the good that the human being carries out.
There are so many people in the world who go through life believing themselves to be good people. They deceive themselves by comparing themselves with the worst criminals in history to portray themselves as gentle pigeons. However, the comparison to know whether we are good or not is not to use the bad as a reference, but to use the good. Who is good? In Mark 10:18, the Lord Jesus gives us the answer, So Jesus said to him, “Why do you call Me good? No one is good but One, that is, God.” Therefore, God Himself is the standard of goodness.
If there is only one good and God, then all human beings, without exception are not good. Paul describes it very well in Romans 7:14-23, For we know that the law is spiritual, but I am carnal, sold under sin. For what I am doing, I do not understand. For what I will to do, that I do not practice; but what I hate, that I do. If, then, I do what I will not to do, I agree with the law that it is good. But now, it is no longer I who do it, but sin that dwells in me. For I know that in me (that is, in my flesh) nothing good dwells; for to will is present with me, but how to perform what is good I do not find. For the good that I will to do, I do not do; but the evil I will not to do, that I practice. Now if I do what I will not to do, it is no longer I who do it, but sin that dwells in me. I find then a law, that evil is present with me, the one who wills to do good. For I delight in the law of God according to the inward man. But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
From Romans 7:14-23 we can extract the impediments we have to want and do good: we are carnal, we are sold to sin, we do not understand what we do, we do not do what we want, we do what we hate, who do things is the sin that dwells in us, in our flesh does not dwell in the good, to do good is not in us and the law of sin is in our members. In that sense, being dominated by sin according to our own nature, only the intervention of God leads us to love and do good.
We are even unable ourselves to realize that we are wrong and we are doing wrong. Again, it is God’s intervention that convinces us of our error. John 16:7-8 says, Nevertheless I tell you the truth. It is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I depart, I will send Him to you. And when He has come, He will convict the world of sin, and of righteousness, and of judgment.
Only the Spirit of God puts in us the conviction that we are sinners. Once inside we are convinced of our filthiness, the Holy Spirit places in us the desire to repent of our sins and to make the step of faith to seek the righteousness of God by converting us to Jesus Christ, accepting grace and making him our Lord. God bless you.
