What does the Bible say about continuing in grace?

The Apostle Paul encourages believers to 'continue in the grace of God' as seen in Acts 13:43. This request seems strange at first, yet it reflects the understanding that, due to human nature and depravity, we are prone to rely on ourselves rather than on God's grace. Continuing in grace means to hold fast to the true gospel and to the promises of God, recognizing that our salvation and spiritual vitality depend wholly on His grace. Without a continual reliance on grace, we risk believing in vain, as Paul warns in 1 Corinthians 15:1-2.
