In both the times of David and today, there are talkers and then there are doers . . . those who seek God with their whole heart. God doesn't want actions for show, he is looking for those with a sincere heart. Psalm 50 makes this clear. He will answer those who serve him in truth (v 15,) but those who are just making a show are doomed for destruction. (v 22) s97bf8bc

Jesus may have had this Psalm in mind when he was giving John the Beloved in his warning to the church at Laodicea in Revelation 3:16 when he told them their lukewarmness, their hypocrisy, would cause them to spew them out. This was also the same warning given to Israel in Leviticus 18:28 by God, if their actions and hearts weren't in line with his word the land would "vomit" them out.

God has always been looking for those who will worship him in spirit and in truth (John 4:24,) for those whose hearts, words, and deeds line up, for those who have an active faith like Abraham (Genesis 6:15.)

The key to becoming a man after the heart of God like David is given in Psalm 50 (v 14 and 23) and more clearly stated in Psalm 100:4, we draw near to God by thanking him for his goodness and all he has done for us, coming into his gates with thanksgiving and into his courts with praise. Psalm 150 the perfect capstone to a book about giving praise to God.
