Read Acts 1:8
8 But you are to be given power when the Holy Spirit has come to you. You will be witnesses to me, not only in Jerusalem, not only throughout Judea, not only in Samaria, but to the very ends of the earth!” (JBP)
The old saying describes evangelism as one beggar telling another beggar where to find bread. It is a useful reminder that witnessing to our faith is not some boastful exercise whereby we triumphantly declare how we have mastered life. Any true Christian witness is an exercise in humility and weakness. We know how much we need grace. We know we have received it. We would love others to do likewise.
We witness as disciples. And disciples are literally ‘learners’. We are not finished products. We model humility and growth, not perfection. We do not have all the answers, but we know enough to trust the grace of God expressed in Jesus. Our mixed goodness points to the everlasting goodness of Jesus.
And we don’t merely witness as individuals. The life of the Christian community is meant to be a witness in itself. Let the world see how life can be so much better when Jesus takes the reins. The church is meant to be a working model of what God wants to do with the rest of society. This means that not only do we have to seek to be good models of Christian living in ourselves, but also that we need pay attention to the corporate life of the church. Is it distinctive in a positive way?
Evangelism is a lot more than throwing clumps of Bible texts at others. It requires sensitivity, wisdom, perseverance. Thankfully, as our text reminds us, God gives us his Holy Spirit to empower us to do what otherwise we would be unable to do.
