The age old question, “What came first, the chicken or the egg?” can be applied to Psalm 15. If you were to ask any random non-Christian what is required to be a Christian they will inevitably say that you must live a moral life, in other words, you must be good enough to belong to what they see as the Christian “club”. Thankfully that answer is incorrect, as no one can be good enough to earn their way into God’s family. Instead, as we are told in Ephesians 1:5, we are adoptedinto God’s family because “the gift of God is eternal life in Christ Jesus our Lord.” Romans 6:23. However, once we have been given the gift of life, having been adopted into God’s family, we will begin to exhibit the family traits.
In Psalm 15 David sings about some of the character traits that God’s children will increasingly display in their lives.
