What is the significance of the Lord adding to the church?

The Lord's addition to the church, as mentioned in Acts 2:47, reflects His sovereignty in the salvation process. The phrase 'such as should be saved' implies that God is actively fulfilling His purpose in drawing His elect to Himself. This crucially informs our understanding of church growth, highlighting that it is not reliant on human effort but rather on God's intention and timing. Every new believer is a testament to God's grace and His plan for the body of Christ, demonstrating that He is continuously working to fulfill His promises.
