In life we find that we are often trying to justify ourselves. For example when applying for a job and preparing a CV to show that we are the best candidate. When it comes to the psalmist in this passage, David appears to be justifying himself to God. He is asking God to publicly vindicate him. The meaning of the word ‘blameless’ however is not ‘perfect’ or ‘sinless’. It is used to show his trust in God which has not faltered.

This psalm is an encouragement for God’s people to keep trusting him in all situations knowing that the Lord is absolutely committed to his people. The foundation of David’s life does not rest on his blamelessness but on God’s character. For Christians it is what Christ has done for us. The cross is the perfect display of God’s love and truth. This is why Christians want to walk in his way.

Thanksgiving leads to the praise of the Lord. David’s faith has shaped his choices and this enables him to stand. We see this in verse 12. If David had trusted in his ‘blameless’ life he would not have asked God for mercy (verse 11). Instead of justifying himself David is pointing us to the God who has justified him by faith. Faith looks to Jesus Christ and what he has accomplished for us. Only in him can we stand confidently and securely.
