What does Psalm 16:11 mean?

Closing his psalm, David thanks the Lord for showing him the way of life that leads to heaven. There is nothing drab or boring about heaven. It is a place of fullness of joy and unending delights. The greatest joy comes from being in Jesus' presence. First Thessalonians 4:17 promises that believers will be with the Lord forever. We will see Him face to face, and we will be like Him (1 John 3:2). Every believer will have a body like His glorified body (Philippians 3:20–21). In heaven we will be free forever from sin, sickness, sadness, and dying. We will enjoy a reunion with our Christian loved ones and friends. We will not be burdened by our present experiences of restricted time and space.

Heaven is an attractive place. Revelation 21—22 describes it as far beyond the glories of any place on earth. It has gates of pearl and streets of gold. Paul, who was caught up to heaven, calls it "paradise" (2 Corinthians 12:2–3). Even when death seems likely (Psalm 16:8–10), those who have put their faith in Christ can look forward with hope and joy.
