Hello Pastor!
@Daniel9v9 
Thanks for your gracious response.
Ngl, I don't even want to study or think of taking the Lord's Supper because of the terrible warnings. I need to be certain before I take it.
The dilemma l'm having (you may be already aware of it) addresses a few separate and yet interwoven questions, namely (1) the apparent contradiction between God's universal saving will and His election, and (2) the relationship between our possibility of falling away and monergistic perseverance.
And the statement from John 6:37-40. It says no man can come to Him unless the Father grants it and the Son will lose none that come. If God truly had a desire to save all, it would make sense He would grant all salvation but that's not true. Lastly, if the Perseverance of the Saints is true because the statement in John 6, that would mean the doctrine of Evanescent Grace is real. God could be giving people a false faith and they wouldn't know it. This disturbs me and it makes me really question His love for His creation.
Hey, no problem!
The short-ish answer
God is always good and true to His Word, even if we don’t quite understand the science of it. God’s ways and wisdom are infinitely higher than ours (1 Corinthians 1:25, Psalm 92:5), and we have to honour that. (1 Corinthians 13:12)
Both Election and Preservation have their own place and function in the theological framework that Scriptures give us, and they are to be taken as articles of faith (things that must be believed or trusted in) and for our comfort (they should not be abused in any way that causes anyone to doubt or reject God's grace). So, how we understand it and how we apply it, is just as important as the doctrine itself. Simply, Election and Preservation is a gift, but a gift can be abused.
Both God
and His works are rightly apprehended through faith. We cannot scientifically discern the Trinity, for example, but yet, we believe it, because that's the truth that God has graciously revealed about Himself. In the same way, God's
work is also apprehended through faith (Salvation: Romans 10:17; Creation: Hebrews 11:3). All miracles are apprehended through faith (trust) and not reason (which is corrupted by sin). So, God and His salvific work are both articles of faith. They are matters of trust. And even though we cannot understand it in full, we can understand it sufficiently. We don't understand everything about God, but we understand enough to recognise Him as our God and Saviour.
This is all to say, the doctrines, while they may have an outward appearance of being contradictory, they are most certainly not. They simply reveal to us that God is good and righteous at the same time, and that it's not one or the other.
Illustration
Suppose a drunk beggar, in his sleep, received a great gift from a kind and loving king. When he woke up to see the gift granted him, he can either trust that it is for him, or he can disbelieve that it is for him or believe the gift to be fake, and reject it.
This illustration is lacking, and I wouldn't press it too far, but what I want to show in very simple terms is that there is a way in which we can passively receive God's grace, unmerited, and at the same time be able to resist it. God grants salvation, from beginning to end (monergism), but we can abuse it (sin).
The long answer
God's Word is like medicine
It brings salvation to those who have faith, but it condemns those who in sin rejects God's grace. However, it's the same Word, and only one truth. So, just as penicillin may heal some, it can cause harm to others who are allergic to it. This is important to appreciate because how God's Word is applied to us is closely connected to the doctrine itself. That is, not only does the Bible present us with the doctrine of Election, but it always presents it as a doctrine of comfort. It is never applied to cause uncertainty or given to unrepentant people. Same with Preserverance; it is only applied to believers.
So, in a silly but somewhat easy to understand way, we can put Election and Perseverance in the pile of doctrines for believers, and we can put Damnation and warnings against sin in the pile of doctrines for unbelievers. This is a Law and Gospel distinction. The Bible does not force the Law on burdened sinners, but graciously extends the Gospel. Likewise, it does not grant the Gospel to unrepentant sinners, but brings the hammer of the Law.
Sin
We are all sinners. Christians, however, are sinners covered in Christ blood. But it's important to understand that sin is not a mere imperfection or sickness, but so deep and terrible that it corrupts everything, even our ability to reason. I think very often when we picture a "sinner", we think of someone who delights in gross sin. God's Word, however, calls even the highest of human virtues (apart from Christ) sin. This extends to piety, experience, and logic; our ability to reason. (Isaiah 64:6, Psalm 19:12)
The use of reason
There is a place for reason in our faith. Just as we use our sinful bodies to proclaim the Gospel, we also use reason to read, learn, and communicate it (1 Corinthians 1:21, 1 Corinthians 1:27).
Where reason falls short, however, is when it attempts to elevate itself above trust in God. This is a sin. There must be room for holy mysteries, because the Bible demands it. And I think, if we, as a Church, can recognise the Trinity as a mystery, it seems arbitrary to me that many cannot also understand His salvific work as a mystery. Basically, we don't reason with miracles, and salvation is the greatest of all miracles. We trust in a miracle, for it is a divine gift graciously given to us, and no greater gift is there than our Lord Jesus Christ, God in flesh.
The work of the Holy Spirit
The work of the Holy Spirit is alien to us. We can't fully grasp His regenerating work, but we can be certain that He accomplishes it and that He sustains us through the Word. Whenever God's Word is communicated to us, we can recognise it as the true Word of God and His pledge and goodwill to us. Likewise, when we receive the Eucharist, we receive the same Gospel, God's pledge and goodwill to us, in tangible form. This is to say, there is a comfort and assurance that comes with the Gospel, but for those who resist the Holy Spirit, who disbelieve in Him and will not receive the Word, those must be called to repentance by the Law.
Conclusion
No one is as loving, merciful, holy, and righteous, as our God - in fact, He alone is the source of these things, and we are not. Therefore, if anyone teaches anything that causes us to question God's goodness or His Word, we can rest assured that this is a doctrine not from God, but from man.
God is the God of peace, who truly died for all, who convicts us of sin, grants us repentance, and creates us in Christ, where the Holy Spirit produces good works in us. We can be free of any burden or uncertainty about our salvation, knowing that Christ is always with us; His love endures forever and His mercies are new every day.
The peace of Christ to you +
