How do we know God's timing is important?

David's long wait from his anointing to his ascension as king highlights the importance of God's perfect timing. It took nearly 20 years from when David was first chosen by God until he was formally recognized by Israel. This teaches us that God's promises, though seen as delayed, are fulfilled in their appointed time for His glory and our benefit. David's example encourages believers to trust in God's timing, even when circumstances seem prolonged or difficult, affirming that He is always in control.
