Hello all.
I've had this question arise in my mind recently, and would like to know a bit more on the topic.
Decisional regeneration, the idea that someone is saved when they ask Jesus Christ into their hearts,
1) Decisional regeneration is the byproduct of synergistic soteriology. (if you don't know what synergism vs monergism is, see here:
Monergism vs. Synergism by John Hendryx

I wholeheartedly disagree with synergism and decisional regeneration. The Bible never describes regeneration or being born again as the result of anything we do. Instead, it constantly reminds us that it is God's work, the result of His grace. In fact, Jesus outright told us that regeneration cannot be controlled, influenced, or otherwise directed by man. (John 3). He likened it to the wind that you see the effects of it, but you cannot control it, He said when the Spirit is regenerating people (ie, converting them and changing their hearts of stone and opening their blind spiritual eyes), "it goes where it pleases..." (again, read the beginning of John 3)
The proof of this (that regeneration cannot be controlled by man) is found in the very name itself (being born again). Nobody controls their first birth. Likewise, nobody controls their second birth. Other analogies the Bible uses for regeneration present this same concept/truth. The Bible describes regeneration as creation - nobody creates themselves, so it must be something God does for us. It also describes regeneration
2) Also, the Bible never,
not a single time, says to "Invite Jesus into your heart". I have no idea where this language or idea came from, but it wasn't from the Bible. It's just a cute little catchphrase that really doesn't mean anything. The Bible urges us to abandon all self confidence and instead, put our full trust in Jesus, the savior, alone. The phrase "invite Jesus into your heart" doesn't even come close to describing what the Bible and the gospel commands us to do (repent of sins and put our faith (trust) in the Savior)
or accept him as their personal Lord and Savior, or however else it is phrased.
Jesus doesn't need our acceptance. We need his. Again, "accept him as lord and savior" was a phrase invented by men that, again, doesn't even come close to capturing how the Bible describes conversion and what our response to the gospel should be.
Where does that idea come from?
Not the bible, that's for sure.
Does God create faith in us to do so, or do we already have it ourselves?
Faith is a gift from God. (Eph 2:8-9, Ph 1:29, and more) He grants it to us, and then we willingly exercise that faith. That's how God saves us. Another way you could describe this is that God regenerates us (ie, causes us to be born again, spiritually resurrected when we were dead (Eph 2), and the natural result is that we have faith in Jesus.
Life is to breathing as regeneration is to faith.
It is the natural business of the person who is alive to breath, and likewise, it is the natural response of the person who is spiritually alive to have faith in Christ.
By fallen nature, we are unregenerate (ie, spiritually dead - Ephesians 2:1-3) and unbelievers. But out of sheer mercy and grace, God intervenes and saves us by regenerating us (ie making us alive, spiritually). (Ephesians 2:4-5)
If God hadn't done this for us, we would still be unbelievers today, headed for the hell we deserve.
In fact, the only reason anyone at all is saved and going to heaven is because God does this. That is why salvation is by
grace.
Regeneration.

While we're at it, what do we mean by "faith" in the first place?
Biblical faith means "trust". It doesn't refer to merely blindly believing something without evidence. For example, faith in Santa Claus (or "believing that Santa exists") is not the same kind of faith as faith in Jesus Christ. Biblical faith is more like faith in a parachute. You jump out of the plane and you have faith that the parachute will save your life. So your faith here is literally that you are putting all of your trust in something else. When we have faith in Jesus, we are trusting that His death, burial, and resurrection has and will save us.
This passage nicely sums up the true description of salvation:
Titus 3:3ff
At one time we too were foolish, disobedient, deceived and enslaved by all kinds of passions and pleasures. We lived in malice and envy, being hated and hating one another.But when the kindness and love of God our Savior appeared, he saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit, whom he poured out on us generously through Jesus Christ our Savior, so that, having been justified by his grace, we might become heirs having the hope of eternal life.
Break this passage down:
1) We were sinners and unbelievers
2) But God appeared and saved us, not because of anything we did, but because of his mercy
3) How did he do this? By the washing of rebirth and renewal by the holy spirit <--that's regeneration
We are saved by the sovereign, free, regenerating grace of God. Not by
a decision.
Hope I helped!
