How the brothers in Christ found unity in who they are and how the sisters can as well in The Bible?

2 Timothy 2:1-7,11-12 KJV

[1] Thou therefore, my son, be strong in the grace that is in Christ Jesus. [2] And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also.

[3] Thou therefore endure hardness, as a good soldier of Jesus Christ. [4] No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier. [5] And if a man also strive for masteries, yet is he not crowned, except he strive lawfully. [6] The husbandman that laboureth must be first partaker of the fruits.

[7] Consider what I say; and the Lord give thee understanding in all things. [11] It is a faithful saying: For if we be dead with him, we shall also live with him:

[12] If we suffer, we shall also reign with him : if we deny him, he also will deny us:

2 Timothy 2:13-14 KJV

[13] If we believe not, yet he abideth faithful: he cannot deny himself. [14] Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers.

1 Timothy 2:12 KJV

[12] But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence.

1 Timothy 2:13-15 KJV

[13] For Adam was first formed, then Eve. [14] And Adam was not deceived, but the woman being deceived was in the transgression. [15] Notwithstanding she shall be saved in childbearing, if they continue in faith and charity and holiness with sobriety.

1 John 3:10-11 KJV

[10] In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother. [11] For this is the message that ye heard from the beginning, that we should love one another.

1 John 3:10 (NIV)

This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love their brother and sister.

Daniel 3:16-28 (KJV)

16 Shadrach, Meshach, and Abednego, answered and said to the king, O Nebuchadnezzar, we are not careful to answer thee in this matter.

17 If it be so, our God whom we serve is able to deliver us from the burning fiery furnace, and he will deliver us out of thine hand, O king.

18 But if not, be it known unto thee, O king, that we will not serve thy gods, nor worship the golden image which thou hast set up.

19 Then was Nebuchadnezzar full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abednego: therefore he spake, and commanded that they should heat the furnace one seven times more than it was wont to be heated.

20 And he commanded the most mighty men that were in his army to bind Shadrach, Meshach, and Abednego, and to cast them into the burning fiery furnace.

21 Then these men were bound in their coats, their hosen, and their hats, and their other garments, and were cast into the midst of the burning fiery furnace.

22 Therefore because the king's commandment was urgent, and the furnace exceeding hot, the flames of the fire slew those men that took up Shadrach, Meshach, and Abednego.

23 And these three men, Shadrach, Meshach, and Abednego, fell down bound into the midst of the burning fiery furnace.

24 Then Nebuchadnezzar the king was astonished, and rose up in haste, and spake, and said unto his counsellors, Did not we cast three men bound into the midst of the fire? They answered and said unto the king, True, O king.

25 He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God.

26 Then Nebuchadnezzar came near to the mouth of the burning fiery furnace, and spake, and said, Shadrach, Meshach, and Abednego, ye servants of the most high God, come forth, and come hither. Then Shadrach, Meshach, and Abednego, came forth of the midst of the fire.

27 And the princes, governors, and captains, and the king's counsellors, being gathered together, saw these men, upon whose bodies the fire had no power, nor was an hair of their head singed, neither were their coats changed, nor the smell of fire had passed on them.

28 Then Nebuchadnezzar spake, and said, Blessed be the God of Shadrach, Meshach, and Abednego, who hath sent his angel, and delivered his servants that trusted in him, and have changed the king's word, and yielded their bodies, that they might not serve nor worship any god, except their own God.
