John Calvin on the Security of Election

For there is not a more effectual means of building up faith than the giving our open ears to the election of God, which the Holy Spirit seals upon our heart while we hear, shewing us that it stands in the eternal and immutable goodwill of God towards us; -- John Calvin

For there is not a more effectual means of building up faith than the giving our open ears to the election of God, which the Holy Spirit seals upon our heart while we hear, shewing us that it stands in the eternal and immutable goodwill of God towards us; and that, therefore, it cannot be moved or altered by any storms of the world, by any assaults of Satan, by any changes, or by any fluctuations or weaknesses of the flesh. For our salvation is then sure to us, when we find the cause of it in the breast of God. Thus, when we lay hold of life in Christ, made manifest to our faith, the same faith being still our leader and guide, our sight is permitted to penetrate much farther, and to see from what source that life proceeded. Our confidence of salvation is rooted in Christ, and rests on the promises of the Gospel. But it is no weak prop to our confidence, when we are brought to believe in Christ, to hear that all was originally given to us of God, and that we were as much ordained to faith in Christ before the foundation of the world, as we were chosen to the inheritance of eternal life in Christ.

Hence, therefore, arises the impregnable and insubvertible security of the saints. The Father, who gave us to the Son as His peculiar treasure, is stronger than all who oppose us; and He will not suffer us to be plucked out of His hand. What a cause for humility then in the saints of God when they see such a difference of condition made in those who are, by nature, all alike! Wherever the sons of God turn their eyes, they behold such wonderful instances of blindness, ignorance and insensibility, as fill them with horror; while they, in the midst of such darkness, have received Divine illumination, and know it, and feel it, to be so. How (say they) is it that some, under the clear light, continue in darkness and blindness? Who makes this difference? One thing they know by their own experience, that whereas their eyes were also once closed, they are now opened. Another thing is also certain, that those who willingly remain ignorant of any difference between them and others, have never yet learned to render unto God the glory due to Him for making that difference.  Calvin's Calvinism, Section I.

And amazingly, the Thirty-nine Articles of Religion also upholds that the doctrine of predestination and eternal election is a source of great security and comfort to the believer.  Odd that so-called "Calvinists" these days doubt the security of the believer and do not preach or teach the doctrine of unconditional election as a source of comfort and security:

Article XVII:  Of Predestination and Election

Predestination to life is the everlasting purpose of God, whereby, before the foundations of the world were laid, He hath constantly decreed by His counsel secret to us, to deliver from curse and damnation those whom He hath chosen in Christ out of mankind, and to bring them by Christ to everlasting salvation as vessels made to honour. Wherefore they which be endued with so excellent a benefit of God be called according to God's purpose by His Spirit working in due season; they through grace obey the calling; they be justified freely; they be made sons of God by adoption; they be made like the image of His only-begotten Son Jesus Christ; they walk religiously in good works; and at length by God's mercy they attain to everlasting felicity.

As the godly consideration of Predestination and our Election in Christ is full of sweet, pleasant, and unspeakable comfort to godly persons and such as feel in themselves the working of the Spirit of Christ, mortifying the works of the flesh and their earthly members and drawing up their mind to high and heavenly things, as well because it doth greatly establish and confirm their faith of eternal salvation to be enjoyed through Christ, as because it doth fervently kindle their love towards God: so for curious and carnal persons, lacking the Spirit of Christ, to have continually before their eyes the sentence of God's Predestination is a most dangerous downfall, whereby the devil doth thrust them either into desperation or into wretchlessness of most unclean living no less perilous than desperation.

Furthermore, we must receive God's promises in such wise as they be generally set forth in Holy Scripture; and in our doings that will of God is to be followed which we have expressly declared unto us in the word of God.  (Article 17).
