Psalms 2 is a good reminder for us to reflect and meditate on the powerful nature of God's divine mercy and grace toward those who are blessed. It is also a powerful consolation of God's just divine judgment and condemnation upon those who set themselves up as heathens. It is a royal messianic promise to us. It also reminds us that we are not to judge those - this is only reserved for God alone.
Seeking out wise counsel means we open ourselves up to listen to our own self-talk and bring those thoughts to God and seek His wise counsel and wisdom.
