How do we know true happiness is found in Christ?

In Psalm 1, we see that the blessed man is one who does not walk in the counsel of the ungodly but delights in God's law. This indicates that true happiness comes from being in right relation to God, which is only possible through Jesus Christ. The sermon emphasizes that Christ is the 'blessed man' described in the psalm. He perfectly obeyed God's law and offers His righteousness to believers. Therefore, when we are in Christ, we partake in this blessing and experience true, lasting happiness that the world cannot provide.
