"All the believers were together and had everything in common. Selling their possessions and goods, they gave to anyone as he had a need." NIV translation
Would you give up something that you had to help a fellow Christian in need? That is what these verses are talking about. The early church took care of each other because they thought of each other as brothers and sisters in Christ. There was persecution among the early believers and so they banded together to spread the gospel. They even sold things they had and did not need in order to help out their family of believers. Would we, as Christians, do the same? That question can help you to assess where you are at in your walk with the Lord.
"Every day they continued to meet together in the temple courts. They broke bread in their homes and ate together with glad and sincere hearts, praising God and enjoying the favor of all people. And the Lord added to their number those who were being saved." NIV translation
Does this sound like the church of today? At this time, they were meeting together every day. People had to notice that they took this Christian thing seriously and that it was the priority in their lives. They were praising God and those around them did not have to guess whether they were Christians or not because it was obvious in their actions.
Because of their example, people probably asking questions about why they were acting the way they were which gave them the opportunity to share the message of Jesus.
When was the last time that you stood out so much that people asked you about Jesus? That is a question that we should be asking ourselves.
