God created all living organisms in kinds: one kind will never change into another kind. For example, the wolf kind (wolves, dogs, jackal, coyotes) will always remain the wolf kind, and will never change into another kind of animal like the big cats. No fish can ever change into an amphibian or into something else. Not only the fossil record, but practical breeding experiments have proven that. We know from genetics that there is no mechanism by which the genetic recipe of a kind of animal can be changed.
What does that have to do with the Bible and God? God created life, so it should be logical that He employs those principles in His kingdom. One of them is the fixity of kinds principle. For example, we understand from Scripture that initially all angels were with God. They saw, served and worshipped Him. The archangel, Lucifer, rebelled and seduced millions to follow his example (Revelation 12:9). They are known as the fallen angels, kept in darkness for judgement, or still helping the devil to seduce mankind. They cannot repent and go back to God, because they are 'fixed' in their position. The holy angels have also been 'fixated' after their decision to remain loyal to God. Thus we see the principle of the fixity of kinds with the angels: the holy remain holy, the unholy remain unholy.
The moral of the story is that they were able to exercise their free will. No thinking, talking creature of God, angels or humans, were ever deprived of their free will. While alive people also have a choice to make: to serve God or not. Deciding to serve God is not only a mental decision, but must be followed by works of faith. To become a born-again believer is not only to accept Jesus' exchange of the shame of the cross, but also to live His life of consecration and holiness. 'Since we have these promises, dear friends, let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God' (2 Corinthians 7:1). After death, however, people are 'fixed.' In the same way the angels were fixed in their positions after they had exercised their free wills, it will be for human beings. What we are at death, we will be in the new life. Are we believers when we die, we will be with Jesus. Are we unfaithful when we die, we will join the unfaithful devil and his angels in hell.
The important thing to remember is that this fixity has to do with our state when we die. Many people think it is enough to accept Jesus, live as they like and go to heaven. The Bible has many commands about holy living, getting rid of the old man, not gossiping, being jealous, stealing, murdering, lying, et cetera. If those things were not important, God would not have warned us about them. We know that it has to do with the eternal planet of peace where such things will not be allowed. Therefore we are told to get rid of them here, precisely because of the principle of fixity of kinds. If righteous living was not important, God wouldn't have bothered us with it. The tragedy is that many 'saved' people think it is alright with God to betray a spouse, engage in pornography, gossip, or steal, not realizing they are playing with deadly fire. Here we can repent, but after death there is no second chance.
A test for fixity of kinds: If it were not so, God wouldn't have commanded us to repent here.
If only salvation was necessary to inherit the kingdom of God, we would only have had a command to repent, and then would have been told to live as we like.
- Why is it important for us to take note of what fixation means? We will be part of the Bride of Christ. Marriage is about knowing somebody and loving that person. Without the Bible, the Word of God, nobody can know the Lord, Jesus, or the Holy Spirit. Without the Holy Spirit it is impossible to understand the Word. Without the Holy Spirit and the Word, it is virtually impossible to pray.
- Do you want to know if you have a relationship with the Lord? Look at your Bible. Do you read it, or stash it away? Loving somebody means we get to know that person. Jesus' character is expounded in the Bible. It is there we learn about Him.
- Do you have a relationship with the Holy Spirit? Then it is impossible that you will not read your Bible, since the Holy Spirit will always glorify Jesus, and we only know and learn about Jesus in the Scriptures.
- Do you ever pray? Not! How do you want to marry a person you don't speak to?
What is the message?
- A person who has a living, active, interesting, satisfying relationship with Jesus through the Holy Spirit and the Word of God, can be sure of one thing: he won't be caught unawares when he dies and sees Jesus: it will be love continued, since he knew Jesus before death.
- The person who has no relationship, but trusts that he has been saved, will find Jesus a complete stranger. It is unfortunate that that person will probably get the biggest shock of his life: he will not be in heaven. He will be among the strangers, who hated, rejected and scorned Jesus and His death on the Cross.
Those who think accepting Jesus without a relationship with Him, will safeguard them on the day of judgement are seriously deluded. In their laziness and comfort they forgot that God's mercy is unlimited here, but that those who love God must obey Him. God is not a fool. He knows when people want both sides of their bread buttered: accepting Jesus, but living as they like. They are opportunists liable to betray Him and they will never see the inside of heaven. It is a heavy price to pay for laziness.
