Originally Answered: What does it really take for a person to be saved from hell?
You must be born again.
The whole "easy believe-ism" is a lie. And when some people try to sell it that way, other people become disillusioned about it.
In reality, getting saved is not easy. It requires some real soul searching. A person must come to a very difficult realization, and that is that they are "spiritually bankrupt." And that there is no good thing in them. It is a realization that they are sinners, and hopelessly lost. Most people do not reach that conclusion easily. It is like a death. And it reaches their very core. Their heart.
In fact, before anyone can be born-again, they must first die, in a sense.
There is nothing "easy" about that.
(I wish I could underline the part below that says, "For you have died.")
===================== (Note Reference Below)
"If then you have been raised with Christ, seek the things that are above, where Christ is, seated at the right hand of God. Set your minds on things that are above, not on things that are on earth. For you have died, and your life is hid with Christ in God. When Christ who is our life appears, then you also will appear with him in glory.
Put to death therefore what is earthly in you: fornication, impurity, passion, evil desire, and covetousness, which is idolatry. On account of these the wrath of God is coming. In these you once walked, when you lived in them. But now put them all away: anger, wrath, malice, slander, and foul talk from your mouth. Do not lie to one another, seeing that you have put off the old nature with its practices and have put on the new nature, which is being renewed in knowledge after the image of its creator." (Colossians 3:1-10)
I'm not sure what you mean by "Lordship."
Jesus must be the "Lord" of your life. That is just another way of saying that you are not your own boss. When you are born-again, Jesus is now the "boss" of your life. This affects everything you do. It changes how you see things, and it changes your behavior. It changes how you think.
I'm not saying Christians are perfect. We stumble, like anyone else. We make mistakes. But overall, we strive to stay on the right track.
============== (Another verse)
"Because, if you confess with your lips that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For man believes with his heart and so is justified, and he confesses with his lips and so is saved." (Romans 10:9)
