Your birth was no mistake. Your parents may not have planned you, but that does not mean God did not plan you. He works even through human error and failings, and he was not surprised by your birth. In fact, He expected it. It is not fate, nor chance, nor coincidence that you are breathing at this very moment. You are alive because God wanted you to.
God functioned every single part of our body. He custom made each and every single body just the way He needed it. He intentionally chose your race, the color of your skin and every other feature.
He planned the days of your life in advance, choosing the exact time of your birth and death. Where you would be born and live. This means our day of birth, race, and nationality are no accident. He worked it all for His purpose, living no detail to chance.
Regardless of the circumstances of your birth or who your parents are, God had a purpose in creating you. He knew the weaknesses of the two individuals. While some children may be unplanned by their parents, God had planned for them.
God’s intentions take into account human mistakes, even sin. God does not cause or approve of sin or evil, He is able to redeem all situations and use them for his own good.
God never does anything accidentally, and He never makes mistakes. He has a justification for everything He establishes. Every single thing, living and nonliving things, were planned by God for a reason. This shows that every person was designed with a purpose in mind.
