We cannot overcome sin by our own efforts. We receive salvation by making a life-changing commitment to Christ, not merely by accepting doctrines or joining an organization. At age 33, Jesus was arrested by the Romans, who were responding to the demands of an angry mob. He suffered a cruel death on a cross and was buried. Then, according to the Bible, he rose again and later miraculously ascended into heaven.
Intentions matter just as much as effects.
But I say to you that everyone who hates his brother shall be liable to judgment. We distinguish sin from temptation. Human nature is corrupted by sin, and you cannot be good by simply following your natural instincts in their present, damaged form. Temptations to sin are sure to come. God is faithful, and he will not let you be tempted beyond what you can bear.
