Miracles reveal Jesus as Savior.

"Jesus answered and said unto him, Verily, verily, I say unto you, Ye seek me not for the signs which ye saw, but for ye did eat of the bread, and were filled.
Work not for the food that perishes but for the food that remains for everlasting life which the Son of Man will give you; For God the Father sealed him "(John 6: 26,27).
The signs that God shows through miracles of healing, financial prosperity, restored marriage, liberation from vices, depression, evil spirits, etc., are to awaken our faith in Jesus.
With the faith that God awakens us, then, we voluntarily decide to seek Him for an eternal relationship, from here on earth to heaven.
The faith that gives us spiritual understanding is food that remains, it is the bread from heaven, it is Jesus revealing himself as savior, it is the way, the directions, it is the will of God. They are the teachings of the Holy Spirit.
Whoever can hear and see Jesus through signs, have faith awakened, and believe, that is, decide to follow him, to confess him, to assume the understanding he has received, then, that person is saved.
To be saved means to be transformed in our spirit, to be a new creature, to be dependent on God, to be guided by Him, to be instructed about salvation, all the blessings and duties that Jesus conquered on the cross.
To be saved means to have access to knowledge about the kingdom of God, to have the food that remains, to have the spirit of the word, faith, to have Jesus show us the mysteries of heaven, to have a life in communion with the Father.
To be saved is to be reconciled to God. It is to come back to have faith in Jesus as Savior.

God bless us with faith in Jesus.
