What does the Bible say about preparing for eternity?

The Scriptures clearly instruct us on the eternal nature of the soul, emphasizing that our earthly lives are temporary. In James 4:14, we are reminded of the vapor-like quality of our existence, which serves as a call to prepare our hearts for eternity. Preparation includes recognizing our need for salvation through Jesus Christ, the reality of eternal life, and the urgency of living in light of that truth. Every believer is encouraged to invest in spiritual matters, seek God earnestly, and ensure that their lives reflect the gospel, ultimately leading to eternal communion with God.
