What does the Bible say about a believer's life in Christ?

In John 14:19, Jesus declares, 'Because I live, you shall live also,' emphasizing that the divine life granted to believers is deathless and secure. Unlike Adam, whose life depended on his own righteousness and power, believers' lives are anchored in the righteousness of Christ and upheld by God's power. Our lives are hidden in Christ, providing an assurance that is more secure than Adam's innocence. This assures us that no matter our imperfections, we have access to God's inexhaustible grace through Christ, who holds all fullness.
