Which We Have Seen and Heard Acts 4:20 Sermon
Gospel Summary: Acts 4:20 records the bold testimony of believers who could not help but speak of Christ because they had seen His power and heard His truth. This sermon calls the church to rejoice in salvation, to witness without fear, and to proclaim the Lord Jesus Christ to a lost and dying world. True conversion changes a sinner’s desires, fills the heart with love for the brethren, and produces a life that speaks “the things which we have seen and heard.”
The Core Message
1. Salvation Brings a Real and Noticeable Change
The preacher emphasizes that when a person is saved, he is no longer living only in the flesh but is quickened by the Spirit of Christ. The Holy Ghost brings new desires, new affections, and a new love for the things of God. Salvation is not merely a religion; it is a divine transformation that makes Christ precious.
2. A Saved Man Cannot Help Speaking of Christ
Acts 4:20 is the heart of the message: when believers have truly seen and heard the Lord, they cannot remain silent. The testimony of grace naturally flows from a changed heart. The preacher recalls how he immediately told others when he got saved, because the joy of redemption could not be contained.
3. Christian Witness Is Personal, Practical, and Unashamed
The sermon repeatedly urges believers to tell their families, co-workers, neighbors, and even strangers what Christ has done. Whether handing out gospel tracts, inviting someone to church, or speaking a word for the Lord in everyday life, every Christian is called to be a witness. The message is plain: if we are saved, we should live like it and speak like it.
4. God Uses Common People to Do an Eternal Work
The preacher testifies that God saves sinners from all walks of life, calls some to preach, and uses others as faithful witnesses. No man is higher than another at the foot of the cross, and the Lord is no respecter of persons. The church ought to welcome the broken, the poor, and the unlikely, remembering that every soul matters to God.

Application & Invitation
The lesson of this message is simple: if Christ has saved you, tell somebody. Let your home, your workplace, your church, and your daily conversation reflect what the Lord has done in your soul. If you have never been saved, you need the Lord Jesus Christ more than you need anything else in this world. Repent of your sins, believe the Gospel, and trust the Lord Jesus Christ as your personal Savior today; He alone can forgive, save, change, and keep you by His grace.
