What does the Bible say about being courageous?

In Joshua 23:6, Joshua exhorts the people of Israel to be 'very courageous to keep and to do all that is written in the book of the law.' This call to courage is essential as it enables believers to stand firm against the temptations and threats that arise in a world that often opposes God's truth. Courage not only involves physical strength but also moral fortitude, as one must uphold the honor of God's word amidst societal pressures to conform. It is through God's grace that we can cultivate this courage, enabling us to stand up for our Faith even when faced with challenges.
