Which is why we need Jesus, our perfect Substitute. @troyer, even IF someone were able to live a perfect life for a day, it wouldn't make up for their past. We're all under a death sentence already for the sinful deeds we've already done, and no amount of "perfect" living today or in the future can erase that. Does this answer your question(s)? The good news is that our heavenly Father loves us so much that He made a way for us to be saved in spite of our sinfulness: He gave us His Son, His only Son Jesus, to take our sins and guilt upon Himself, to die our death for us, so He could give us His eternal life. All we have to do is acknowledge our need, our sinfulness, and accept this exchange by faith.can never aspire to the purity and holiness that is required to enter heaven.
