How does the Holy Spirit make believers fit for heaven?

The role of the Holy Spirit is pivotal in the believer's transformation and fitness for heaven. As described in 1 Corinthians 3:16, believers are the temple of God, indicating that the Holy Spirit dwells within them. This indwelling empowers and enables believers to live in accordance with God’s will. It is through the work of the Spirit that we are sanctified, allowing us to grow in holiness and spiritual maturity. Furthermore, the Spirit teaches and guides believers into all truth, revealing the deep things of God to those who are fit to receive them (1 Corinthians 2:10-12). This intimate relationship with the Holy Spirit assures believers of their place in heaven, as it continually conforms them more into the image of Christ.
