What does Psalm 49:2 mean?

No one is left out of the psalmist's invitation to hear his message (Psalm 49:1). It was for everyone, including the lowest class of society and the highest class. It was for rich and poor together.

Similarly, God's invitation to accept His love and everlasting life is for everyone who will believe in His Son (John 3:16–18). When Jesus ministered on earth, He excluded no one from His love and message. He promised, "Whoever comes to me I will never cast out" (John 6:37). He showed compassion and forgiveness to outcasts and influential people alike. He cleansed lepers (Mark 1:40–42); forgave despised tax collectors (Luke 19:8–10), an adulteress (John 8:10–11), a Samaritan woman (John 4:39), a crucified and dying thief (Luke 23:42–43), His own Roman executioners (Luke 23:33–34); and offered salvation to a rich young man (Matthew 19:21–23). He shed His blood on the cross for the sins of the whole world (1 John 2:2).

Christ's earliest followers carried His message of love and forgiveness to everyone, without exception. They healed a lame beggar (Acts 3:1–7) and shared the gospel with a wealthy businesswoman (Acts 16:11–15). The apostle Paul even declared the gospel to philosophers, governors, and kings (Acts 17:15–31; 24—26).
