Why is saying 'If the Lord wills' important for Christians?

Saying 'If the Lord wills' is a crucial proclamation for Christians as it acknowledges the sovereignty of God over our plans and future. In James 4:15, it is stated, 'For that ye ought to say, If the Lord will, we shall live, and do this, or that.' This expression serves as a reminder that, despite our intentions and desires, ultimately, God is the one who directs our steps (Jeremiah 10:23). Recognizing this helps cultivate a posture of humility and dependency on God rather than self-reliance. It encourages believers to be flexible in their plans, understanding that God knows better than we do what is best for us and guiding us according to His divine purpose.
