How do we know we are heirs of God's inheritance?

The assurance of being an heir of God's inheritance comes through faith in Jesus Christ. As Peter writes, believers are those 'kept by the power of God through faith unto salvation' (1 Peter 1:5). This assurance is not based on our works but on God’s election and the redemptive work of Jesus Christ. The testimony of Scripture, and the indwelling Holy Spirit, provide evidence of our status as God's elect. In Romans 8:17, believers are affirmed as heirs of God and joint heirs with Christ, signifying our intimate relationship with Him.
