It is not just words, it is God's word combined with His Holy Spirit that makes the difference.
The Holy Spirit plays a crucial role in delivering faith to believers through the preaching of the Word of God. It is to be believed that the Holy Spirit works through the proclaimed Word to create and sustain faith in the hearts of listeners. ( Monogistic )

The Spirit dwells in believers, giving them spiritual motivations, right judgment, and a desire to avoid sin. However, this does not diminish the importance of the Spirit's work in the act of preaching and the life of the church.

The work of the Holy Spirit is connected closely to His use of the Word of God in oral, written, and sacramental forms to create and sustain the church, convert sinners into God's children, and preserve them in faith. 

Baptism is not just plain water, but it is the water included in God’s command and combined with God’s word. Holy Baptism works forgiveness of sins, rescues from death and the devil, and gives eternal salvation to all who believe this, as the words and promises of God declare. Christ our Lord says in the last chapter of Mark: “Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.” (Mark 16:16)

Certainly not just water, but the word of God in and with the water does these things, along with the faith which trusts this word of God in the water. For without God’s word the water is plain water and no Baptism. But with the word of God it is a Baptism, that is, a life-giving water, rich in grace, and a washing of the new birth in the Holy Spirit, as St. Paul says in Titus, chapter three: “He saved us through the washing of rebirth and renewal by the Holy Spirit, whom He poured out on us generously through Jesus Christ our Savior, so that, having been justified by His grace, we might become heirs having the hope of eternal life. This is a trustworthy saying.” (Titus 3:5–8)

What does the water in Baptism indicate, that the Old Adam in us should by daily contrition and repentance be drowned and die with all sins and evil desires, and that a new man should daily emerge and arise to live before God in righteousness and purity forever. St. Paul writes in Romans chapter six: “We were therefore buried with Him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life.” (Rom. 6:4)

The Eucharist ( The Lord's Supper ) is the true body and blood of our Lord Jesus Christ under the bread and wine, instituted by Christ Himself for us Christians to eat and to drink.

The holy Evangelists Matthew, Mark, Luke, and St. Paul write:Our Lord Jesus Christ, on the night when He was betrayed, took bread, and when He had given thanks, He broke it and gave it to the disciples and said: “Take, eat; this is My body, which is given for you. This do in remembrance of Me.”

In the same way also He took the cup after supper, and when He had given thanks, He gave it to them, saying, “Drink of it, all of you; this cup is the new testament in My blood, which is shed for you for the forgiveness of sins. This do, as often as you drink it, in remembrance of Me.” What benefits is this eating and drinking? These words, “Given and shed for you for the forgiveness of sins,” show us that in the Sacrament forgiveness of sins, life, and salvation are given us through these words. For where there is forgiveness of sins, there is also life and salvation.

Certainly not just eating and drinking do these things, but the words written here: “Given and shed for you for the forgiveness of sins.” These words, along with the bodily eating and drinking, are the main thing in the Sacrament. Whoever believes these words has exactly what they say: “forgiveness of sins.” 

Prior to partaking in the Lord's table, it is essential to engage in prayer, express gratitude, and maintain unwavering faith in the divine words conveyed in the Holy Bible. Approach this sacred act with utmost reverence and heed the caution issued by St. Paul regarding unworthy receiving.
