Jude 24-25
24 Now to him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, 25 to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen.
The perfect corollary verse for Phil 1:6 (a previous memory verse), God has taken great care to reveal and to confirm His electing and saving power. There are other verses that confirm His and only His ability to elect, save and allow persevering (see 1 Cor 1:8, Heb 12:2 as well), but one cannot be too confident of what God and God alone can accomplish.
Think about this for a second, for those convinced that God needs a hand to save you: YOU WILL DIE FACING THE LORD THE SAME WAY YOU CAME TO HIM. What exactly do I mean by that? If you came to Him repenting and seeing the fact that you are sick in need of a physician (Matt 9:12; Mark 2:17 and Luke 4:23) and based on His Merit and Jesus finished work on the cross (remember when He said “it is finished” tetelestai) believing that it, and it alone would satisfy His wrath, you will die even more convinced that He alone is able to save you based on a life being changed by the Spirit that He gave you when you came to Him (Eph 1:13). But if you came to Him on Your merit and what you can do and after a life of bad performances you realize nothing has changed (having a form of godliness but denying the power, 2Tim 3:5), you die hopelessly lost without Christ, dead in your sins with no hope. You have no hope because rather than seeing the hope revealed in the Scriptures (Rom 15:4), so that by the power of the Holy Spirit (that you don’t have) you may abound in hope (see Rom 15:13). Your trying to earn your way to Heaven has left you with no hope because you rejected the only One Who gives hope along with His Holy Spirit guaranteeing your salvation.
May I persuade you along with the apostle Paul in 2 Corinthians 5:11 “Knowing therefore the Terror of the Lord, we persuade men:” be reconciled with God (Eph 2:16, Col 1:20) through Christ’s finished work on the cross and not your vain attempts to earn Heaven.
