@SW-User I disagree with you entirely. Reality itself contradicts your opinion. Over the years, since the world began, we have had trillions of people walk the earth, till date. And just like you, a majority lived in wanting to do good and to make the world a better place than they met it, yet the 21st century is recorded as being the bloodiest till date. Going with your ideology, ought not the world have been, as to response, made better, since the billions of people past who lived only to do good and make it a better place? Do we not see then that this ideology/mission is just grasping for the wind??
Man is inherently sinful - prone to do evil than good. (Do not care limit evil to just stealing and killing, please. Telling lies, holding grudges, and disrespect elders are equally evil as those.) The majority of his decisions is circled to his selfish ambitions. He is a SLAVE to sin(ning). No matter the amount of good he does, he is not lacking in evil. People then suffice with the morbid excuse of "No one is perfect". Inexcusable! If a plate were not perfect, we would not eat with it (lest we eat parts of it, or our food were to spill away); if a white shirt were not perfect, we would not wear (lest we fee under-dressed and every eye gaze upon the stain on it mockingly). Yet we permit it as normal for ourselves. A foolish excuse.
Every religion but Christianity teaches "salvation/perfection/acceptance by works", but Christianity teaches that nothing we do can make us whole/free us from the bonds of sin holding us captive - and we see this is true, because no man wills to live perfect/totally good and successfully executes it all the days of his life.
The common mistake perceived is that Christianity is a book of dos and donts. NO. The bible states the dos and donts, yes, but its primary reason for that, and its primary message, is showing how we indeed are unable to fulfil all this, but like a dog we unashamedly, & like a slave we unwillingly, walk back to sinful living. Hence the reason for Christ: He, born without sin, even despite walking among sinners, and being tempted daily just as we are, yet lived in total obedience to God, void of the blot of sin. Being perfect, He thus was able to be sacrificed on the behalf of all - for a sinner cannot rescue another sinner from damnation, since they both are damned; but the pure is able to lay His life down for the impure.
And so, as Christ was crucified on that cross, He absolved the sin of the world, and became appropriation for our sins, satisfy the wrath of God - because God, being just and holy, though He is love and He loves us, cannot permit that transgressors of the law go scot-free. So Christ, His only begotten son, perfect and guiltless, died in our place instead, that any who would believe in Him should escape the judgement of transgressions, which is hell, and be bought into the family of God, being no longer enemies of God but sons and daughters.
That is how great a love God has for us. Though He owes us not mercy, He yet decided to show mercy, providing, by the death & resurrection of His son, a way of redemption for sinners. By that we know He loved/s us, that while we yet sinners, Christ died for us.
Hence my reason for saying there are TWO religions ALONE: Christianity and then others. Search every religion and you will see - of the emissaries/fore-runners of each and everyone, in Christianity alone do you find that a creator laid His life down for the salvation of His creations. Every other one demands that the followers earn their salvation (by following a set of rules and ordinances).
So yes, we should worry in pleasing that supernatural being, God, because He is our creator, He is Holy, and if we continue in sin, rejecting his FREE GIFT of GRACE, He will give to us what is rightfully due us - JUSTICE (an eternity in hell - where there is no end, but wailing and gnashing of teeth day and night.)
Ironically, Jesus spoke more of hell - giving loud warnings, as a mother to her her rebellious child - than He did of Heaven. How terrible a thing it then be.
Christianity is not a religion. It is a relationship.
