We are truly heartened by examples of faith, courage, love, compassion, purity and enthusiastic service to our Lord.
Lydia, of Thyatira, (Acts 16:13-15), was an energetic lady with a beautiful heart whose affection was set on "heavenly things" (Colossians 3:2). Paul and company met this business lady and her household who were worshiping God on the Sabbath day by the river. Lydia, thus, had prior knowledge about our Creator, and Father who had made a promise to bless all nations through the seed of faithful Abraham.
Paul, Silas and Luke studied with them about the manifestation of God's grace in the person of Jesus Christ. They would be taught that Jesus, of Nazareth, fulfilled the messianic prophecies in the Old Testament. Lydia and her household would learn that Jesus has become prophet, priest, and king, and, as priest, has offered Himself for the sins of the world (1 John 2:2).
On the one hand, Lydia heard about the wonderful things God had done on behalf of each of us who are worthy of eternal death due to our sins; she would hear how God lovingly provided a means whereby we could be washed, sanctified and justified (1 Corinthians 6:11). This is God's grace revealed in the gospel (good news message).
On the other hand, Paul's message included matters Lydia should "attend to" to be a recipient of God's forgiveness of her past sins; these crucial matters would serve as an expression of her faith in trusting God's system of making men righteous. This is faith.
Lydia said, "If ye have judged me to be 'faithful to the Lord,' come into my house and abide there" (Acts 16:15). How did Lydia demonstrate that she was faithful to the Lord"? Was it not her obedience (that came from a heart of love and trust) upon gladly receiving heaven's instructions?
The doctrine of Christ includes repentance and baptism unto the remission of sins (Mark 16:16; Acts 2:28) at which time the believer is buried into Christ's death (Romans 6:3-4) and is cleansed by the blood of the Lamb. Lydia was faithful in attending to these things spoken by Paul and was promptly baptized into Christ (Acts 16:15).
You and I may follow in the steps of the energetic servant of God by attending promptly unto the things spoken by the Lord and the men of God recorded on the pages of the New Testament of Jesus, the Christ. We'll be forevermore glad we did!
