God has created everything good including all of humanity. But, we are all born with a propensity to sin and the free will to resist that sin or embrace it. St. Paul addressed this in the following:
Romans 3:23 -For all have sinned, and do need the glory of God.
If one uses their free will to sin they are separating themselves further away from an eternity with God. Without repentance that will die in condemnation but if they live a life of repentance they will be saved by God’s grace.
Now, we know that God’s mercy is without limits but He is also just. Acknowledging this teaching we realize that we do not know who will be saved for sin may be private or public, both kinds of sin are known to the sinner and to God and it is by this unrepentant sin that we will be judged. We do know that all are called to salvation but that few respond fully to the call. We know that the path to salvation comes to a narrow gate where many will be unable to enter.
Mat 22:14- For many are called, but few are chosen.
Luk 13:24- Shall seek... Shall desire to be saved; but for want of taking sufficient pains, and being thoroughly in earnest, shall not attain to it.
Here are some of the fallacies of believing that all will be saved or that all good people will be saved, other than the fact that none of us are worthy of salvation on our own. It is natural for people to want to depend on God’s mercy alone for salvation but as I said before God does not provide mercy at the exclusion of justice. There are also those who believe that God will even save those who have no desire to be saved. This is an example of mercy without justice for it would not be just to save someone without a desire to be saved. He does not give mercy to those who do not desire it from Him. He allows us and indeed prompts us to come to Him by preparing us all to surrender to His law written on our hearts. This law is sufficient and without it no one would be convicted to follow Him and desire Him. Our conscience is formed by this law which is intuitive and not learned by hearing His Word or by anything but recognizing His creation which the Bible says is sufficient knowledge to come to faith and desire Him. In this we surrender to Him and become obedient to His will to desire Him. By that and a devotion to repent of our sins is sufficient for salvation. It is the path to the narrow gate that Scriptures teach. It is His grace through the Holy Spirit that we are called and convicted of His will which is contained in His law circumcised upon our hearts. His grace is not forced upon anyone but one must surrender to Him to receive it. It is a free gift that one can refuse and we must recognize that many will refuse His gift and fail to surrender to His law which has the result of one condemning them. So, as much as we desire as Christians that God’s mercy be extended to all people both good and bad, it will only be given to those who surrender to His law and recognizing His sovereignty while living in His will. It is by having a desire for His Grace and repenting when we fail through our sinfulness which results in His mercy.
For those who believe that all good people will be saved we must understand that none of us are good enough. We all sin through thought, word and deed. As a result it is only through Christ’s salvific work that we can be justified by our contrite repentance and be deserving of His mercy.
