Wow...........much wrong here, much. First being the statements you give were not only stated in Joshua............
Let us start with this one:
“I have plans to prosper you…” not said to us.
What Jesus said that was for ALL who believe on Him
John, Chapter 10:
9I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
10The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
I'd say Jesus has plans to "prosper us."
“Be fruitful and multiply…” not said to us.
Jeremiah, Chapter 29
6Take ye wives, and beget sons and daughters; and take wives for your sons, and give your daughters to husbands, that they may bear sons and daughters; that ye may be increased there, and not diminished.
Psalms 127:3 - Lo, children are an heritage of the LORD: and the fruit of the womb is his reward.
Proverbs 22:6 - Train up a child in the way he should go: and when he is old, he will not depart from it.
Proverbs 17:6 - Children's children are the crown of old men; and the glory of children are their fathers.
Isaiah 54:13 - And all thy children shall be taught of the LORD; and great shall be the peace of thy children.
Matthew 18:10 - Take heed that ye despise not one of these little ones; for I say unto you, That in heaven their angels do always behold the face of my Father which is in heaven.
Mark 10:14 - But when Jesus saw it, he was much displeased, and said unto them, Suffer the little children to come unto me, and forbid them not: for of such is the kingdom of God.
Ephesians 6:4 - And, ye fathers, provoke not your children to wrath: but bring them up in the nurture and admonition of the Lord.
The WHOLE REASON God created male and female was for the purpose of procreation. Not just men and women, but ALL of His Creations! All that walk on the earth, fly in the sky, or swim in the seas!
Let us be honest and admit that to properly interpret Scripture, one MUST be a Sanctified Believer. That is one who is filled with the indwelling presence of the Holy Spirit.
To suggest that God did not intend for US, the Church to have children is simply a childish view of Scripture..........
There is ONE GOSPEL............I will never subscribe to the two Gospel ideology
