A Bird in the Hand is Worth Two in the Bush - birds have provided considerable insight that influence aircraft design - different types of wings that adapt to thrust, drag, lift, and weight - the four basic forces involved in flight. Delta wings were inspired by birds of prey like the peregrine falcon. This bird’s ability to curve its wings backward and align them close to its body reduces drag, allowing it to swoop down with rapid velocity. The delta wing structure is especially common among high-speed aircraft like the B-2 Spirit. This stealth bomber has many similarities to a peregrine falcon in both shape and performance

Inspired by God’s creation mandate in Genesis 1:28, humans across the centuries have sought ways to optimize processes, solve problems, and ultimately “subdue” the world for our benefit. 

The quest to observe and record the laws of nature has taught us many helpful concepts in a variety of fields, particularly in topics related to science and technology.

One example is aerodynamics, the study of forces and resulting motion of objects through the air.

Specifically, birds have provided considerable insight into the principles that influence aircraft design. 

These incredible animals were created with different types of wings that adapt to thrust, drag, lift, and weight — the four basic forces involved in flight. 

Delta wings, for instance, were inspired by birds of prey like the peregrine falcon.

This bird’s ability to curve its wings backward and align them close to its body reduces drag, allowing it to swoop down with rapid velocity.

The delta wing structure is especially common among high-speed aircraft like the B-2 Spirit. 

This stealth bomber has many similarities to a peregrine falcon in both shape and performance. 

It features sleek wings that minimize drag and improve speed, and its ability to hit marked targets parallels the skill of a falcon on the hunt.

Because the plane was designed for covert missions, it employs sophisticated aerodynamics to reduce radar cross-section and boost maneuverability — similar to the precision and agility of a swooping bird through the air. 

Its design also incorporates features that reduce its radar signature, so though not completely silent like a falcon, the B-2 operates with a high level of stealth.

Furthermore, just as falcons adjust their wings to accommodate flight conditions, this aircraft has geometric wings that can be configured for different flight phases.

Clearly, the design of peregrine falcons has influenced the unique engineering of the B-2 Spirit bomber — one of the most iconic planes in the U.S. military arsenal.

If human inventions like bird-inspired aircraft illustrate design, how much more the birds themselves! 

To this point, Romans 1:18–25 conveys the idea that everyone, including scientists, can recognize the God-designed complexity of nature.

Our experiences with the handiwork that we see around us make it impossible to deny His agency.

As we note the use of design elements borrowed from the natural world, it’s not “Mother Nature” (the creation) that deserves the credit but God (the Creator).

Truly, He is the God “who created the heavens and stretched them out, who spread forth the earth and that which comes from it, who gives breath to the people on it, and spirit to those who walk on it” -  (Isaiah 42:5).

Workmanship is emphasized in this passage as well as Psalm 19:1–6. 

Nature exhibits characteristics that are exclusive to the design agency observed in the efforts of artists or engineers. 

However, since nature's workmanship cannot be of human origin, it is reasonable to attribute causality to God’s handiwork.

A God Who Understands - He who was larger than the universe became an embryo. Jesus Christ was deity in diapers. Jesus humbled Himself and walked this earth and breathed our air and lived our life. God as a man, God on the cross, and God rising again. He never ceased to be God. But He did lay aside some of the privileges of deity and died our death. We have a God in Heaven who understands what it’s like to walk through this life. He literally felt our pain. He went through all of this for us

A Purpose for Everything Under the Heavens - you are not here by accident. Everything God has ever made was created with a specific design and function in mind. There is a great Designer who planned every detail of who you are and the glorious plan you are to fulfill. You were not born simply to occupy space — to eat food, go to the bathroom, sleep, and get up the next morning to start the same dull, boring routine all over again. No. There is a reason you are here on this earth. You have a God-assigned, God-given purpose

Life is meaningless without the Lord sitting on the throne of our lives - the cycle of life and death is unaffected by a man's position, power, prosperity, or poverty, for all are destined to die. Man's failure is a result of man's own self-effort, striving, and human pride, because God is excluded from people's lives. When God is put in His rightful position in our heart, then we are kept by His almighty power. When wisdom, skill, prosperity, and power, are under God's sovereign influence and control, then life has meaning
