How do we know the concept of suffering for Christ is true?

The truth of suffering for Christ is underscored throughout the New Testament, particularly in passages like John 15:20 where Jesus states that if they persecuted Him, they will persecute His followers. This concept aligns with the early apostles' experiences, such as Paul and Silas, who rejoiced in their suffering because they understood it was part of their divine calling. Their imprisonment illustrates the gospel's power to advance even amidst adversity; as stated in Romans 5:3-5, enduring trials builds spiritual maturity and deepens our relationship with God. This framework of suffering as a pathway to growth and witness is integral to the sovereign grace perspective.
