In man’s very best attempt at being good, we fail to ultimately please ourselves enough to bring upon redemption. We inherently know the impossibility of that, which is why there are numerous religions.
There are some that chart out the ways to earn redemption and others that state a soul is reincarnated in an effort to try again to be good enough for redemption. Still there are others that simply offer pleasures that are only earthly and never redemptive. There is only one God who can gift redemption and His name is Jesus Christ. The only One to offer true Hope.
