True success is not measured by wealth, fame, or power, but by obedience to God's Word. When Joshua faced the daunting task of leading Israel into the Promised Land, God did not promise him military genius or superior weapons. Instead, God gave him a book and a command: meditate on it day and night. Success would come not through human strategy but through constant meditation on Scripture that leads to obedience.

Meditation is not mere reading or study—it is pondering, chewing, absorbing God's Word until it shapes how we think, speak, and act. The phrase "shall not depart out of thy mouth" suggests that Scripture should be so familiar, so precious, that we speak it constantly—in our prayers, our conversations, our decisions. When God's Word governs our hearts, our lives bear fruit: wisdom in decisions, peace in trials, and spiritual victory over enemies.

The promise is conditional: "that thou mayest observe to do." Meditation without obedience is useless. We must not only know what Scripture says but do what it commands. When we align our lives with God's Word, He calls it prosperity and success—not necessarily material wealth, but the deep satisfaction of living in His will, the peace that comes from walking His path, and the eternal rewards of faithful obedience.

Prayer: Lord, teach us to meditate on Your Word day and night. Write it on our hearts, put it on our lips, and work it into our lives through obedience. Let true success be found not in worldly achievement but in walking faithfully with You. Amen.
