I'm a Deuteronomy 30 and Romans 10 believer. Those two passages should end the Calvin vs Arminius debate.
Deuteronomy 30:1
So it shall be when all of these things have come upon you, the blessing and the curse which I have set before you, and you call them to mind in all nations where the LORD your God has banished you,
Deuteronomy 30:6
Moreover the LORD your God will circumcise your heart and the heart of your descendants, to love the LORD your God with all your heart and with all your soul, so that you may live.
Deuteronomy 30:11
For this commandment which I command you today is not too difficult for you, nor is it out of reach.
12 It is not in heaven, that you should say, 'Who will go up to heaven for us to get it for us and make us hear it, that we may observe it?
13 "Nor is it beyond the sea, that you should say, 'Who will cross the sea for us to get it for us and make us hear it, that we may observe it?' 14 "But the word is very near you, in your mouth and in your heart, that you may observe it.
15 See, I have set before you today life and prosperity, and death and adversity;
Deuteronomy 30:19
I call heaven and earth to witness against you today, that I have set before you life and death, the blessing and the curse. So choose life in order that you may live, you and your descendants,
Now look at Deu 30:19 very carefully. It says the CHOICE was set before us, and it tell us to choose. It says "I call heaven and earth to witness" the choice you make.
Rom 8:15-17 NASB 15 For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, "Abba! Father!" 16 The Spirit Himself testifies with our spirit that we are children of God, 17 and if children, heirs also, heirs of God and fellow heirs with Christ, if indeed we suffer with [Him] so that we may also be glorified with [Him.]
Notice the correlation between the choice God tells us to make in Deuteronomy 30:19 and Romans 8:16; he calls heaven and earth to witness, and the Spirit (heaven) and our spirit (earth) to testify (to bare witness) of the choice we make.
Romans 10 simply tells us that Deuteronomy 30 is all about faith and the salvation that comes from it:
Romans 10:5
For Moses writes that the man who practices the righteousness which is based on law shall live by that righteousness.
6 But the righteousness based on faith speaks as follows: "DO NOT SAY IN YOUR HEART, 'WHO WILL ASCEND INTO HEAVEN?' (that is, to bring Christ down),
7 or 'WHO WILL DESCEND INTO THE ABYSS?' (that is, to bring Christ up from the dead)."
8 But what does it say? "THE WORD IS NEAR YOU, IN YOUR MOUTH AND IN YOUR HEART"--that is, the word of faith which we are preaching,
9 that if you confess with your mouth Jesus [as] Lord, and believe in your heart that God raised Him from the dead, you will be saved;
10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
11 For the Scripture says, "WHOEVER BELIEVES IN HIM WILL NOT BE DISAPPOINTED."
Isaiah 28:16
Therefore thus says the Lord GOD, "Behold, I am laying in Zion a stone, a tested stone, A costly cornerstone [for] the foundation, firmly placed. He who believes [in it] will not be disturbed.
So we know that the human choice talked about in Deuteronomy 30 ... the one that is "not too difficult to make" and the one that is "not made in heaven" is the choice for salvation.
