Psalm 1:1-2: Guard Your Mind
Psalm 1:1-2: Blessed is the man who walks not in the counsel of the wicked, nor stands in the way of sinners, nor sits in the seat of scoffers; but his delight is in the law of the Lord, and on his law he meditates day and night. 
If you wanted to protect your house, one measure you might take is to hire a guard to stand outside your door. Psalm 1 functions as a guard at the front door of the Psalms, warning that we must embrace God’s truth or face “ultimate judgement.”  The three negatives in verse one warn against departing God’s ways, and verse two reflects the importance of absorbing “Scripture as a whole” to stay on the LORD’s path, off the way to destruction. 
Because Psalm 1 is God’s truth, ignoring its instructions leads to condemnation.  Minds that reject Scripture are doomed.  The “law” in verse two is the whole system of God’s teaching and faithful living.  The consequences for disregarding the Bible’s covenantal law by the power of the Holy Spirit are catastrophic for believer and unbeliever alike, though true Christians are spared from eternal damnation.  Therein is the issue: we all fail! Our only hope is to cling to the one who faithfully lived out Psalm 1: Jesus Christ. If we trust in Him as our only means of forgiveness from the Father’s just wrath, then we can grow in His counsel, maturing in His way, as we await the day when we will sit with Him in glory.
