None.
Just shut up, and be the most graceful human soul you can be.
Thats it.
If you think after living a graceful loving life that god will send you to hell just because you didnt go into a church or a mosque, etc. Then the God you deem so highly isnt as benevolent as you believe.
Stop focusing on how other people are living, stop focusing on what they eat, or who they love.
Focus on yourself, and being the most kind of productive human soul you can be for the other humans and nature around you.
It's that simple.
Lee Stobel identified key components of salvation - "Believe", "Receive" and "Become". Each part matters - this is how he puts it (hint - better than I could!)
1. Believe
"As someone educated in journalism and law, I was trained to respond to the facts, wherever they lead. For me, the data demonstrated convincingly that Jesus is the Son of God who died as my substitute to pay the penalty I deserved for the wrongdoing I had committed. And there was plenty of wrongdoing. I’ll spare myself the embarrassment of going into details, but the truth is that I had been living a profane, drunken, self-absorbed, and immoral lifestyle. In my career, I had backstabbed my colleagues to gain a personal advantage and had routinely violated legal and ethical standards in pursuit of stories. In my personal life, I was sacrificing my wife and children on the altar of success. I was a liar, a cheater, and a deceiver. My heart had shrunk to the point where it was rock hard toward anyone else. My main motivator was personal pleasure—and ironically, the more I hungrily sought after it, the more elusive and self-destructive it became. When I read in the Bible that these sins separated me from God, who is holy and morally pure, this resonated as being true. Certainly God, whose existence I had denied for years, seemed extremely distant, and it became obvious to me that I needed the cross of Jesus to bridge that gulf. Said the apostle Peter, “For Christ died for sins once for all, the righteous for the unrighteous, to bring you to God” (1 Peter 3:18). All this I now believed. The evidence of history and of my own experience was too strong to ignore."
2. Receive
"Every other faith system I studied during my investigation was based on the “do” plan. In other words, it was necessary for people to do something—for example, use a Tibetan prayer wheel, pay alms, go on pilgrimages, undergo reincarnations, work off karma from past misdeeds, reform their character—to try to somehow earn their way back to God. Despite their best efforts, lots of sincere people just wouldn’t make it. Christianity is unique. It’s based on the “done” plan—Jesus has done for us on the cross what we cannot do for ourselves: he has paid the death penalty that we deserve for our rebellion and wrongdoing, so we can become reconciled with God. I didn’t have to struggle and strive to try to do the impossible of making myself worthy. Over and over the Bible says that Jesus offers forgiveness and eternal life as a free gift that cannot be earned (see Rom. 6:23; Eph. 2:8–9; Titus 3:5). It’s called grace—amazing grace, unmerited favor. It’s available to anyone who receives it in a sincere prayer of repentance. Even someone like me. Yes, I had to take a step of faith, as we do in every decision we make in life. But here’s the crucial distinction: I was no longer trying to swim upstream against the strong current of evidence; instead I was choosing to go in the same direction that the torrent of facts was flowing. That was reasonable, that was rational, that was logical. What’s more, in an inner and inexplicable way, it was also what I sensed God’s Spirit was nudging me to do. So on November 8, 1981, I talked with God in a heartfelt and unedited prayer, admitting and turning from my wrongdoing, and receiving the gift of forgiveness and eternal life through Jesus. I told him that with his help I wanted to follow him and his ways from here on out. There were no lightning bolts, no audible replies, no tingly sensations. I know that some people feel a rush of emotion at such a moment; as for me, however, there was something else that was equally exhilarating: there was the rush of reason."
3. Become
"After taking that step, I knew from John 1:12 that I had crossed the threshold into a new experience. I had become something different: a child of God, forever adopted into his family through the historical, risen Jesus. Said the apostle Paul, “Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come” (2 Cor. 5:17). Sure enough, over time as I endeavoured to follow Jesus’ teachings and open myself to his transforming power, my priorities, my values, and my character were (and continue to be) gradually changed. Increasingly I want Jesus’ motives and perspective to be my own. To paraphrase Martin Luther King Jr., I may not yet be the man I should be or the man, with Christ’s help, I someday will be—but thank God I’m not the man I used to be! Maybe that sounds mystical to you; I don’t know. Not so long ago it would have to me. But it’s very real to me now and to those around me. In fact, so radical was the difference in my life that a few months after I became a follower of Jesus, our five-year-old daughter Alison went up to my wife and said, “Mommy, I want God to do for me what he’s done for Daddy.” Here was a little girl who had only known a father who was profane, angry, verbally harsh, and all too often absent. And even though she had never interviewed a scholar, never analyzed the data, never investigated historical evidence, she had seen up close the influence that Jesus can have on one person’s life. In effect, she was saying, “If this is what God does to a human being, that’s what I want for me.” Looking back nearly two decades, I can see with clarity that the day I personally made a decision in the case for Christ was nothing less than the pivotal event of my entire life."
To read the reasons why Lee came to these conclusions you could do plenty worse than read "The Case for Christ" and weigh the issues for yourself.
That was Lee's story. I came to the same place...
You can't save yourself, you need a Saviour.
