There is nothing wrong with wanting to become a better version of ourselves. Self-actualization and reaching our full potential sounds almost Biblical, but it’s not. The Bible doesn’t teach about potential. It teaches us about purpose.
What is the most important part about being a Christian? Is it believing in Jesus, or believing in a particular politician or cause? Most of us would rightly prickle at such a question, but we also struggle with tacking on "extra must-dos" to our faith. So when we encounter fellow believers who support different causes than us, how should we respond? In patience, and love.
