It's really a matter of being baptized when you're old enough to know right from wrong and then living the Christian life to the best of your ability. You won't earn your salvation, it's God's grace that covers us. But God expects effort on our part and will judge us accordingly. Otherwise if it's you'll go to Heaven no matter how you live then many people would do some pretty wicked things. The Christian life is about living your best life so that you aren't harming yourself or others. But you'll never be perfect. You ask for forgiveness when you fail and you move on, trying not to sin. Being of service to others. I don't believe it's constantly skipping through fields of daisies while singing Kumbaya. You need yellow tights for that...
