The Bible says that we (believers) have been sealed with the Holy Spirit.
In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that Holy Spirit of promise . . . (Eph 1:13)
And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. (Eph 4:30)
What exactly does it mean to be sealed by the Holy Spirit? It means that upon our salvation, the Holy Spirit has actually come to live within each and every one of us. (Ac 2:38) We are the temple of the Holy Spirit. (1 Cor 6:19) He dwells within each and every Christian.
The word “seal” means to confirm, authenticate, or guarantee something. The presence of the Holy Spirit within us is a potent spiritual connection between us and God. Here are several verses verifying that the Holy Spirit dwells in us.
- Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? For you were bought at a price; therefore glorify God in your body and in your spirit, which are God’s. (1 Cor 6:19)
- Do you not know that you are the temple of God and that the Spirit of God dwells in you? (1 Corinthians 3:16)
- If anyone defiles the temple of God, God will destroy him. For the temple of God is holy, which temple you are. (1 Corinthians 3:17)
The very presence of the Holy Spirit within us confirms and validates our salvation experience, and it guarantees that we do have eternal life. We will spend eternity with the Lord.
