Many churches throughout the world use a Bible reading schedule called a "lectionary." It's just a fancy word meaning "selected readings." Posts like this reflect on the readings for an upcoming Sunday or other Church holiday, as found in the historic one-year lectionary.
Many will speak of the Christian life, that it is something to be hidden in our hearts, as Jesus dwells there, in a private place. While there is a way in which this is true, our Psalm reading describes a sort of Christianity which overflows.
In Psalm 40:10, the Psalmist does NOT hide God's deliverance. Rather, he speaks of it, of God's faithfulness, God's salvation, God's steadfast love. It is the message for "the great congregation." Everyone who is listening gets to know about it.
Our goal, then, is to fill our heart with God's good news to the point that it overflows. The mercy of God is for all who will hear. God's faithfulness is a universal aspect of his character. It is applied to everyone.
As Christians let the Gospel spill over into all their lives, the whole world will come to know God's wonders, for them too.
