The Bible teaches that heaven is the glorious, eternal home of God's elect, where they enjoy perfect, unending communion with the Father, Son, and Holy Spirit. It is a state of complete holiness, peace, and joy, free from all sin, sorrow, and death, which the saints enter after death to await the final resurrection.
Heaven is described as the "house of many mansions" and a "far more exceeding and eternal weight of glory." It is a place where God’s people are fully restored to the likeness and favor of their Creator. According to the 1689 LBCF Ch.31 §1, upon the death of the believer, the soul is made perfect in holiness and enters into the presence of Christ to behold the face of God in light and glory. This hope is not merely a destination, but a Person—the Lord Jesus Christ, who is the source of all our joy. As described in the vision of John, heaven is a place where the curse is no more and the servants of God serve Him in perfect, eternal communion.
In heaven, the joy of the saints is ever-increasing, fueled by the immediate vision and fruition of the Triune God. As noted in the Westminster Larger Catechism Q.90, believers shall be "fully and forever freed from all sin and misery; filled with inconceivable joys, made perfectly holy and happy both in body and soul." This blessed state is made possible only because Christ, our Savior, has purchased this inheritance for us through His own finished work. We do not earn this home by our obedience; rather, we inherit it as adopted sons and daughters because we are united to Christ. It is a place where the deepest longings of the human heart are finally met in the love of the Father, the grace of the Son, and the fellowship of the Spirit.
