Jesus came not just to forgive sins, but to establish God's kingdom on earth. While many Christians focus on getting to heaven when they die, Jesus focused on bringing heaven to earth now. The kingdom of heaven is where God's will is always done, in contrast to our self-built earthly kingdoms. When Peter encountered Jesus and witnessed the miraculous catch of fish, his perspective shifted from seeing Jesus as merely a teacher to recognizing Him as Lord and King. This transformation led Peter to leave everything behind and follow Jesus. We too are invited to change our 'why' in life by seeking God's kingdom first, trusting Him with our lives, and bringing heaven to earth through our daily actions.
