Good correction on Christian living in today’s Psalms:

Psa 4:5  Offer sacrifices in the right spirit, and trust the LORD. 

Offering sacrifices back then is how people communed with God, if they did something bad, Mosaic law said they would have to make some kind of sacrifice, usually some form of live stock, the sacrifice would then cancel out the debt that their sin built up, in other words; sacrifice this goat, and the fact that you said something bad about your neighbor is now forgiven in the eyes of the Lord. 

Sometimes people would just go through the motions of offering sacrifices like, I did this bad thing to ‘so-and-so’, now i am just going through the motions so that bad mark is no longer hanging over my head, it’s like a fake apology.  

Fast forward from when this was written to today, thanks to the New Covenant of Jesus, who became our sacrifice, we no longer need to offer these ritualistic sacrifices of ancient Israel, Christ did all that work for us and when we put our trust in Him, our debts are taken away.  

So with that in mind, we now connect with God, not through sacrifices, but through prayer with His Son and the Holy Spirit as intermediaries, and the Psalmist is saying “pray in the right spirit”, or with a humble heart.  When we pray, we should pray with the contextual understanding that we are passengers, passing from one world to the next, but passage to that next world is only possible by putting our faith in Christ, and the verse ends with the consummate reminder to trust in The Lord, or resigning ourselves to the fact that all the events occurring in this life that we are passing through are designed by God and not man.  At the end of the day, we are to trust in God, and go to Him with a meek and humble attitude.
