Perfect example of unconditional love is the love of parents.
My mother and father love us, their children, unconditionally.
My mother's love for me is manifested through her giving birth to me. For 26 hours she was in labor for me, raised me, worked and sacrificed and nurtured me and raised me in the Fear of God. As she has done with my 3 younger siblings. That is unconditional love.
My father's love for me and my siblings is again, exemplary of unconditional love.
He loves us unconditionally enough to sacrifice his own youth for the acquisition of stability of family.
When my father worked in Saudi Arabia as a Civil Engineer to provide for the family, that was unconditional love. When my father came to the United States and took up medical schooling to better provide for us, that was, again, exemplary of Unconditional Love. He did not have to, but he did so out of selfless love for his children and family. Denying his own comfort for the comfort of those whom he and my mother created. And who bear his name, blood, and gene-seed.
When my mother tells me time and time again, despite my being 24 years old, calling and referring me as "always you are my baby boy!" that is manifestation of a mother's Unconditional love for her son. Her child. Who once lived in her belly, nurtured by her love, flesh of her flesh, blood of her blood.
When my mother tells me, calls me, and texts me asking how I am doing, and reminding me to "Always pray for God's Guidance..." that is again, an exemplary manifestation of UNCONDITIONAL LOVE.
My Father loves me Uncondotionally.
He abounds in joy in me, for I am fruit of his loin. His son. Who bears his mark and his gene seed.
As my earthly father loves me unconditionally, so does my Heavenly Father, FATHER GOD, loves me Unconditionally.
He loved me unconditionally that He sent His only Son, Jesus Christ to save me.
