In the Heidelberg Catechism in question 8 regarding humanity, the question asks…8. Q. But are we so corrupt that we are totally unable to do any good and inclined to all evil? A. Yes, unless we are regenerated by the Spirit of God. Gen. 6:5; 8:21; Job 14:4; Is. 53:6.  John 3:3-5.
In terms of satisfaction before God the answer is spot on, there is nothing that humanity alone can do that would be pleasing to Him regarding God’s holy character, in this sense our nature is considered evil. Humanity, humanly speaking, is on a path of no return. In and of ourselves we are helpless in this regard.
Sure, we do things that have a measure of goodness in them but in terms of purity, the human heart is not only low grade, it also has in it's nature an inbuilt rebellion that is opposed to the holiness of God. As Jesus said in John 3:7 “You should not be surprised at my saying, ‘You must be born again.’”
It’s no good looking inside ourselves for our redemption, the answer is found in another. God has connected with humanity in Christ. For God was pleased to have all his fullness dwell in him… Col 1:19.
In our lostness & spiritual emptiness
God through Christ gives us a new song, an eternal song.
