First law
Lex I: Corpus omne perseverare in statu suo quiescendi vel movendi uniformiter in directum, nisi quatenus a viribus impressis cogitur statum illum mutare. Every body persists in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by force impressed.
There exists a set of inertial reference frames relative to which all particles with no net force acting on them will move without change in their velocity. This law is often simplified as “A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force.” Newton’s first law is often referred to as the law of inertia.

Newton’s First Law (Lex I) which is “Corpus omne perseverare in statu suo quiescendi vel movendi uniformiter in directum, nisi quatenus a viribus impressis cogitur statum illum mutare.” is often simplified as ‘Every body persists in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by force impressed’. Newton’s first law is often referred to as the law of inertia.

An application of this physical law in our Spiritual life could be used to derive what I call the Law of Sinful Inertia. The Law of Sinful inertia states that “everybody persists in their state of  death in trespasses and sins or in moving disobediently on the broad way that leads toward destruction, except insofar as they are compelled to change their lives by the grace and gift of God in the person of Jesus Christ.”

Ephesians 2:1-8 (KJV)
1 And you hath he quickened, who were dead in trespasses and sins;
2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
4 But God, who is rich in mercy, for his great love wherewith he loved us,
5 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
6 And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
7 That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
