“How may I know I have understood the gospel and that I am elect?
“First, by the Word of God having come in divine power to the soul so that my self-complacency is shattered and my self-righteousness is renounced. Second, by the Holy Spirit convicting me of my woeful, guilty, and lost condition. Third, by having had revealed to me the suitability and sufficiency of Christ to meet my desperate case and by a divinely given faith causing me to lay hold of and rest upon Him as my only hope. Fourth, by the marks of the new nature within me – a love for God; an appetite for spiritual things; a longing for holiness; a seeking after conformity to Christ. Fifth, by the resistance which the new nature makes to the old, causing me to hate sin and loathe myself for it. Sixth, by avoiding everything which is condemned by God’s Word and by sincerely repenting of and humbly confessing every transgression. Failure at this point will surely bring a dark cloud over our assurance causing the Spirit to withhold His witness. Seventh, by giving all diligence to cultivate the Christian graces and using all diligence to this end. Thus the knowledge of election is cumulative.

“For we know, brothers loved by God, that he has chosen you, because our gospel came to you not only in word, but also in power and in the Holy Spirit and with full conviction. You know what kind of men we proved to be among you for your sake.

By this we may know that we are in him: 6whoever says he abides in him ought to walk in the same way in which he walked.” – 1 John 2:3-6
