Important things do not come easy in life...
Salvation is received for free but we need to work it out(which needs great effort) with fear and trembling.
(Philippians 2:12"....—continue to work out your salvation with fear and trembling,")
We are to exercise our self towards godliness to grow spiritually.
(1 Timothy 4:7" "... train yourself to be godly.)
Our Lord desires we enjoy good health too...
(3 John 1:2, "Dear friend, I pray that you may enjoy good health and that all may go well with you, even as your soul is getting along well) so we need to eat right, work out, avoid junk food, walk etc.
God's Word says we are to discipline our body and bring it into subjection (this too involves effort)
(1 Corinthians 9:27, "But I discipline my body and bring it into subjection)
All hard work brings a profit,
(Proverbs 14:23 "In all labor there is profit, But idle chatter leads only to poverty.")
Have a blessed day....
