In the life of the early church, we see a dramatic transformation that serves as a blueprint for every believer. We move from the ‘Emmanuel Principle’—knowing God walked amongst us—to the Pentecostal reality that God’s Spirit continues to dwell with us at all times. God’s presence was no longer confined to one human, but available to everyone across space and time.
Before Pentecost, we find the disciples behind locked doors ‘for fear of the Jews’ (John 20:19). They had seen the resurrected Christ but were still hiding. However, after the Holy Ghost descended upon them, those same men stood in the very heart of the city that had crucified their Master and spoke with such authority that the world was turned upside down.
What changed?
They hadn’t gained more physical strength or political influence; they had received a new kind of boldness. This transformation was the fulfilment of a specific promise made by Jesus before his ascension:
‘But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.’ Acts 1:8.
The word power comes from the Greek dýnamis, meaning effective ability or enabling strength. While the term later gave rise to the explosive word dynamite, here it refers to the Spirit-given power to act. It wasn’t speaking to a quiet, internal peace, but a functional, active courage that enables us to do what we could never do in our own strength. For the disciples, it meant the courage to be witnesses of Christ. For us, it may mean the courage to stand for truth in a workplace, to lead a church group with spiritual authority, or to face a personal crisis without collapsing into fear.
One of the most powerful examples of this Pentecostal boldness is found in Acts 4. The apostles Peter and John had been arrested and threatened, yet their response was not to ask for safety, but to seek the Spirit.
‘And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness.’ Acts 4:31.
Notice the sequence: they prayed, the Spirit filled them, and the result was boldness. This tells us that courage is not a personality trait but a spiritual fruit. Even if we’re naturally shy, cautious, or prone to anxiety, when the Holy Spirit is given room to operate in our lives, we develop divine confidence.
The Holy Spirit cures our fear by shifting our source of confidence. When we rely on our own talent, we fear failure. When we rely on our own safety, we fear loss. But the Spirit reminds us that we are the ‘temple of the living God’ (2 Corinthians 6:16).
The spirit of fear is essentially a spirit of bondage that makes us feel like slaves to our circumstances. But the Spirit God gives is one of adoption. It is the Spirit that allows us to cry, ‘Abba, Father’ (Romans 8:15). When we know we belong to the Father, we no longer have to fear the world. A child walking with their father doesn’t fear the barking dog nearly as much. They trust the one holding their hand.
How do we access this today? It begins with the simple request of God to give us the power of the Holy Spirit:
‘How much more shall your heavenly Father give the Holy Spirit to them that ask him?’ Luke 11:13.
True Christian courage is not the absence of fear, but the presence of the Holy Ghost. It is the ‘might by his Spirit in the inner man’ (Ephesians 3:16) that allows us to stand firm when the world is shaking. Today, we don’t just ask God to just take away our frightening situation. We ask him to fill us with the boldness of his Spirit so that we can walk through it with our head held high.
