Curious that there is blessing in being apart and not having!

Blessed is the one who does not…

Blessing comes because we stand with God in integrity, and because we need that blessing to counter life’s temptations.

walk in step with the wicked

The wicked are those convinced they are right, and willing to manipulate their will. They take the moral high ground, but their fruit is not love.
We need God’s grace to walk with him in love, leaving wicked’s forceful arguments.

or stand in the way that sinners take

Sinners deny no desire and refuse no pleasure. This contrasts with God’s faithfulness. Am I willing to wait for God’s fulfilment or driven to satisfy my needs?
We need faith to rest in God content with what he has given and leave the road of temptation.

or sit in the company of mockers,

Mockers laugh at anyone who takes God seriously, so sitting with mockers dulls us to intimacy with Jesus.
We need hope in God to distance ourselves emotionally from those who mock in order to sit humbly and expectantly at Jesus’ feet.

The next verses tells how the Lord establishes and empowers this love, faith and hope in our lives.

but whose delight is in the law of the Lord, and who meditates on his law day and night. That person is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither – whatever they do prospers. [Psalm 1:1-3]
