Who is it who gets to enjoy the presence of God?
Simply put: the righteous. 
But who are the righteous?
This Sunday, we are going to be processing through Psalm 15 and beginning to see who the righteous are: what their character is like, what makes up their relationships, who is their conduct, and how they relate to money. As we do so, we will see a completely different presentation from the wicked that we’ve seen in Psalm 3-14. 
As we do, we will ask: am I righteous? Do I measure up? Do I match the qualifications that God gives for the righteous? 
For, if not, Jesus says: “unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.”
As we are approaching Psalm 15, spend some time thinking through the requirements that God gives and honestly assess your life to see how you measure up to God’s requirements. As you do so, think about how someone who doesn’t match up to God’s requirements could ever possibly expect to be welcomed to God’s table.
This is also a good reminder of the Gospel; for we all only deserve the eternal judgment of God, yet we receive mercy and grace because Jesus was righteous in our place. 
Spend some time thinking about Jesus’ righteous life and how His righteousness is given to you, by faith. Then, think about how your life should look differently because of what Jesus has done for you. Spend some time in prayer, asking God to reveal areas of your life that are not being lived in conformity with holiness and ask Him to convict you of your sin so that you might turn from sin and live out your new identity as a Christian. 
All of this is the beautiful reminder of Psalm 15 that the Lord calls us to live righteously
