The Holy Spirit does the work of sealing the hearts of the saints who have been forgiven of their sins by believing in the gospel Word of the water and the Spirit.
The Holy Spirit works in our hearts according to our faith in the written Word of truth.
1) He bears witness to the fact that the Word of God is true. The Holy Spirit guarantees the hearts of those who believe in the Word of the baptism of Jesus and the Cross. Like this, when one believes in Jesus’ baptism and the blood of the Cross, the One who approves his/her faith as right is God the Holy Spirit. The Holy Spirit works among those who most certainly believe in the written Word. The Holy Spirit approves the faith of those who believe in the gospel of the water and the Spirit. He guarantees, in other words, those who believe that Jesus came to this earth and blotted out the sins of the world with His baptism and blood.
2) The Holy Spirit is with the righteous, and makes them testify the gospel of the water and the Spirit to sinners. In John 16:8-9, Jesus said, “And when He has come, He will convict the world of sin, and of righteousness, and of judgment: of sin, because they do not believe in Me.” The Holy Spirit reaffirms the gospel of the water and the Spirit in the hearts of the righteous (John 14:26). He bears witness of what the Lord has done. He enable us to know that Jesus came to this earth, took upon the sins of the world by being baptized, and died on the Cross, and He allows us to believe in them.
3) He makes us believe in God and to call upon Him. The Holy Spirits makes the righteous pray. Romans 8:15 states, “For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, ‘Abba, Father.’” The Holy Spirit enables the saints to call and believe in God as “Abba, Father.”
4) The Holy Spirit makes us work with the gifts that He has given us. He enables us to do the works of the righteousness of God with His abilities. 1 Corinthians 15:10 states, “But by the grace of God I am what I am, and His grace toward me was not in vain; but I labored more abundantly than they all, yet not I, but the grace of God which was with me.”
5) The Holy Spirit leads us until we enter Heaven. The Holy Spirit enables the righteous to keep their faith until they reach the Kingdom of the Lord, and remains with them as their Teacher.
