For we know brothers loved by God, that he has chosen you, because our gospel came to you not simply with words, but also with power, with the Holy Spirit and with deep conviction. 1 Thessalonians 1: 4-5 (New International Version)
The people of Thessalonica received the Gospel heralded by Paul with joy. Almost immediately, though, persecution ensued, to the point where the Apostle had to leave. The impact of Good News was revealed not just by the response, but also how the church had withstood opposition, and continued to by grow in and share faith. This not only encouraged Paul, but also became an example for all believers.
At the heart of our receiving Good News is also acknowledging that the Lord is the prime mover in the salvation process. Not only did God take our redemption into His own hands by sending Jesus, in the great expression of His love, God also invited us to follow Jesus as Lord and Savior. Then, the Spirit was sent into our hearts, not only to confirm the message, but also to enable us to be living witnesses for the Gospel.
This threefold understanding of salvation is what has kept the Gospel alive for over 2000. We do not decide ourselves to be "saved," but rather embrace what God has done. Salvation is more than the moment of conversion, but also a lifetime of service to the Master. This means we seize every God moment before us, and share the Good news that Jesus Christ is Lord. This, in turn, enables the Spirit to work in another heart for a new relationship with God.
