Not only is the theory of evolution completely contrary to holy scriptures, so is the idea of the survival of the fittest. The Apostle Paul said: "God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are:That no flesh should glory in his presence." 1 Corinthians 1:27-29
The Bible is filled with examples of insignificant people becoming great champions. Noah was not an experienced craftsman when God called him to build an ark. Abram's wife Sarah was not able to bear children when God called him to be the father of a great nation. Gideon was an obscure farmer. Samson was ordinary. King David's great-grandmother, Ruth, was a Moabitis and from outside the nation of Israel. David was a shepherd. The apostles were unlearned fishermen, a hated tax-collector and men of no reputation. From beginning to end, God has not chosen the strong.
For a person to have the notion that he/she is responsible for survival of any sort due to some internal strength or good thoughts is a gigantic mistake and on the edge of blasphemy. It is taking credit for gifts that only the Almighty can bestow.
David said in Psalm 103: "Bless the LORD, O my soul, and forget not all his benefits: Who forgiveth all thine iniquities; who healeth all thy diseases; Who redeemeth thy life from destruction; who crowneth thee with lovingkindness and tender mercies; Who satisfieth thy mouth with good things; so that thy youth is renewed like the eagle's." "Like as a father pitieth his children, so the LORD pitieth them that fear him. For he knoweth our frame; he remembereth that we are dust. As for man, his days are as grass: as a flower of the field, so he flourisheth. For the wind passeth over it, and it is gone; and the place thereof shall know it no more."
O how much we should honor the LORD with praise for all that He does for us, giving Him alone due credit for our survival and whatever strength we have.
