What does the Bible say about the calling of the apostles?

In Matthew 10, we see that the Lord Jesus called His twelve apostles, highlighting their selection and the authority with which He endowed them. This selection was not based on personal merit or qualifications but was a demonstration of God's sovereign grace. The calling of these apostles signifies the initiation of the new covenant, where God’s chosen people are called into His kingdom through the gospel. This is significant as it illustrates that God selects those whom He wills to bring into His fold, transcending human expectations of worthiness.
