Ok, what are your thoughts on Eph 1:13-14 and Rom 8:33-39, just to clarify.
***
Eph 1:13-15
13 In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise,
14 who is the guarantee of our inheritance until the redemption of the purchased possession, to the praise of His glory.
Prayer for Spiritual Wisdom 15 Therefore I also, after I heard of your faith in the Lord Jesus and your love for all the saints,
NKJV
God, Himself, guarantees our salvation based upon our faith in His promise that He has purchased us by His shed blood on the cross. These verses speak for themselves. Who do you think has given us the scriptures? Man or God. If you say man, then who placed the sun and the Moon?
Rom 8:33-39
33 Who dares accuse us whom God has chosen for his own? No one—for God himself has given us right standing with himself.
34 Who then will condemn us? No one—for Christ Jesus died for us and was raised to life for us, and he is sitting in the place of honor at God's right hand, pleading for us.
35 Can anything ever separate us from Christ's love? Does it mean he no longer loves us if we have trouble or calamity, or are persecuted, or hungry, or destitute, or in danger, or threatened with death?
36 (As the Scriptures say, "For your sake we are killed every day; we are being slaughtered like sheep.")
37 No, despite all these things, overwhelming victory is ours through Christ, who loved us.
38 And I am convinced that nothing can ever separate us from God's love. Neither death nor life, neither angels nor demons, neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God's love.
39 No power in the sky above or in the earth below—indeed, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord.
Means what they say. Our victory is through faith in Jesus' work on the cross. Not on what we do but on what Jesus has already done for us.
