How do we know that God's grace sustains the church during persecution?

The assurance of God's grace is a core element of how God sustains His people, especially during persecution. Jesus states in Revelation 2:10 that those who are faithful unto death will receive a crown of life, symbolizing the eternal reward for their faithfulness. This reflects the theological understanding that believers are both sustained and empowered by God's grace to endure hardships. As Peter reminds us in 1 Peter 5:10, after you have suffered a little while, the God of all grace will Himself restore, confirm, strengthen, and establish you. Such assurances affirm that God is actively involved in the lives of believers, enabling them to withstand challenges and remain steadfast in their faith.
