Dynamic Faith (Luke 24:44-53; Acts 1:1-11)

ascension 06

The Apostle Luke gives us two versions of the story of Jesus’ ascension. One thing Luke 24:44-53 and Acts 1:1-11 have in common is that both of them have Jesus promising his disciples that they will receive power from the Holy Spirit. Christians celebrate the ascension of Jesus because he returned to the presence of his Father in order to be with his followers around the world and throughout time, and to give us power through his Spirit.

We can understand the word ‘power’ in a few different ways. Coming from Adelaide, a lot of people immediately think of one of our local Australian Football League teams, Port Adelaide Power. When many people of my generation and younger hear the word ‘power’ we often think of governments or other authority figures who use their ‘power’ for their own benefit or to control others. However, when the Bible talks about ‘power’ it means something different.

The New Testament word for ‘power’ is the same word from which we get our English words ‘dynamic’, ‘dynamo’ and ‘dynamite’. It means strength or an active force which makes things happen. When Jesus promised his followers that they would receive power from the Holy Spirit, he was telling them that he would send them his Spirit to give them the ability or strength they would need in order to do the work he was sending them to do.

There is a lot we could discuss about the power of the Holy Spirit in the lives of believers, but right now I want to focus on the task Jesus gave to his disciples at his ascension. In both Luke’s gospel and the book of Acts, Jesus told his disciples that they would be his witnesses. The Holy Spirit was to give them what they needed to witness to Jesus’ suffering, death and resurrection, and to bring the message of repentance and forgiveness of sins to all people.

It is significant that Paul also uses the word for ‘power’ when he talks about what the gospel of Jesus can do in a person’s life. In Romans 1:16 he writes that the good news of Jesus is ‘the power of God at work’ (NLT). In the same way, in 1 Corinthians 1:18 Paul writes that the message of the cross is ‘the very power of God’ (NLT) for all who are being saved. These passages tell us that the Holy Spirit uses the good news of Jesus to work the power of God in us so we can be Jesus’ witnesses to the world.

The idea of witnessing to Jesus can be scary for a lot of Christians for a range of reasons. There have been a lot of programs and campaigns developed to try to help churches be more effective in our witnessing. I’m wondering, though, based on what Jesus says in the ascension stories, whether being his witnesses might be a lot simpler that we might think it is.

If the gospel is the way God gives us the Holy Spirit’s power, then it seems to me that living in the good news of Jesus would give us Holy Spirit power to witness to what Jesus has done for us. For example, Jesus says in Luke’s gospel that we will bring the message of repentance and forgiveness to all nations. When the Holy Spirit gives us the power to receive this forgiveness through faith, then the Spirit would also give us the power to forgive others in the same way. Witnessing to Jesus, then, means forgiving people who have wronged us in the Holy Spirit’s power just like God has forgiven us.

We can witness to Jesus in other ways, too. When the Holy Spirit gives us the power to believe that God loves us for Jesus’s sake, then the Holy Spirit also gives us the power to love others in the way Jesus teaches. When the Holy Spirit gives us the power to trust in God’s grace for us in Jesus, then the Holy Spirit also gives us the power to extend that same grace to others. When the Holy Spirit gives us the power to trust that God accepts us because of what Jesus has done for us, then the Holy Spirit also gives us the power to accept others in the same way. I could go on and on, going through each of the fruits of the Spirit (Galatians 5:22,23) or Paul’s definition of Love (1 Corinthians 13:4-8a) to show how the Holy Spirit gives us the power to trust in God’s goodness and the power to display his goodness in our lives and in our relationships.

The ways in which we live our lives and treat other people are much more authentic and effective ways to witness to Jesus than preaching on a street corner or knocking on doors. There will be times when we will be asked to explain why we live in ways that are different to other people (see 1 Peter 3:15) but even then Jesus promises us that the Holy Spirit will give us the words to say (see Matthew 10:19; Mark 13:11; Luke 12:11). We really don’t need to stress about being Jesus’ witnesses because the Holy Spirit will give us the power we need in whatever opportunities God might give to us.

I would encourage anyone who is intimidated by the possibility of witnessing to others to start with the gospel. Where do we need God’s grace in our lives? Are we looking for forgiveness or healing? Are we lacking love, acceptance, hope or something else in our lives? When we find what we need in Jesus, in his suffering and death for us, or in his resurrection from the dead, God encounters us through the gospel, giving us his Holy Spirit and the power we need to witness to Jesus, not as a theological idea but as our lived reality.

Obviously there’s a lot more that can be said about the power of the Holy Spirit’s power in our lives, but that’s for other times. As we celebrate the ascension of Jesus, it is good for us to remember that we are witnesses to his grace and love in the world. Jesus sends us the Holy Spirit who gives us the power to both believe in his grace and to live out his grace in all our relationships.

That can be a powerful witness.
