Consent was important to Abraham, concerning getting a wife for Isaac.
Genesis 24:8 And if the woman will not be willing to follow thee, then thou shalt be clear from this my oath: only bring not my son thither again.
Rebecca gave her consent to be the bride and go with Elizer, having not seen her husband Isaac.
And they called Rebekah, and said unto her, Wilt thou go with this man? And she said, I will go. Genesis 24:58
The people of Israel made a verbal acknowledgement to agree and consent to the law.
And Moses came and told the people all the words of the LORD, and all the judgments: and all the people answered with one voice, and said, All the words which the LORD hath said will we do. Exodus 24:3
This is a choice, to be made continually.
I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live: Deuteronomy 30:19
And if it seem evil unto you to serve the LORD, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the LORD. Joshua 24:15
Believers of Yeshua, likewise, give consent, and agree to love Yeshua to become his wife.
And likewise as Rebekah did not see her future husband Isaac as she was agreeing to be his wife. Well over 99.99% of Christians consent without having seen the groom, and agree to be his bride.
Whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory: 1Peter 1:8
Yeshua saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed. John 20:29
But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. 1Corinthians 2:9
But, we actually give a verbal sign when we consent and agree to become the Bride of Christ. Everyone who hears the gospel, the invitation, (if they are appropriately moved to repentance and belief by the Holy Spirit) has the option to confess or deny Christ.
Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. But whosoever shall deny me before men, him will I also deny before my Father which is in heaven. Matthew 10:32-33
But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:) Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.) But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; That if thou shalt confess with thy mouth the Lord Yeshua, and shalt believe in thine heart that Yahweh hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Romans 10:6-10
Consent is an important part of the preaching ministry, if people are not willing to listen, we are told to move on, and we are not responsible any longer, as Abraham said, "And if the woman will not be willing to follow thee, then thou shalt be clear from this my oath". Gen 24:8
And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet. Matthew 10:14
And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city. Mark 6:11
And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them. Luke 9:5
