The Bride of Christ
‭‭Mark‬ ‭10:29‭-‬30‬ ‭NIV‬‬
[29] “Truly I tell you,” Jesus replied, “no one who has left home or brothers or sisters or mother or father or children or fields for me and the gospel [30] will fail to receive a hundred times as much in this present age: homes, brothers, sisters, mothers, children and fields—along with persecutions—and in the age to come eternal life.

‭‭1 Timothy‬ ‭5:1‭-‬2‬ ‭NIV‬‬
[1] Do not rebuke an older man harshly, but exhort him as if he were your father. Treat younger men as brothers, [2] older women as mothers, and younger women as sisters, with absolute purity.

‭‭John‬ ‭1:9‭-‬13‬ ‭NIV‬‬
[9] The true light that gives light to everyone was coming into the world. [10] He was in the world, and though the world was made through him, the world did not recognize him. [11] He came to that which was his own, but his own did not receive him. [12] Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God— [13] children born not of natural descent, nor of human decision or a husband’s will, but born of God.

‭‭1 Peter‬ ‭1:22‭-‬23‬ ‭NIV‬‬
[22] Now that you have purified yourselves by obeying the truth so that you have sincere love for each other, love one another deeply, from the heart. [23] For you have been born again, not of perishable seed, but of imperishable, through the living and enduring word of God.

I think these align quite well to say that when we are truly born again as Children of God that we become part of a much larger Spiritual Family.

We begin to Love all our Brothers and Sisters in Christ without favoritism or partiality, beyond just the members of our household and bloodline/heritage.

The Church is our Eternal Family. It says that in Heaven we will know all others as well as be known completely. There may be secrets each of us keep here, beliefs and experiences that keep us divided and separated to a certain degree but we should always strive to bring ourselves and those around us to Unity, Love and Purity in Christ.

As we get to know Christ and the Holy Spirit, our Love for Others begins to transcend Earthly distinctions.

As we Crucify our Flesh and learn to overcome the lusts of the eyes, lusts of the Flesh, and the pride of life, our Love is made pure.

As we confess and repent of all our wrongdoings and impure thoughts, we are delivered from the fear, guilt, shame, etc that usually keeps us all at arms reach for various reasons.
