Why do we work so hard and push ourselves so hard? The reason behind that is important to understand because God is the one who is to be working hard. See Psalm 127.
Unless the Lord builds the house, They labor in vain who build it; Unless the Lord guards the city, The watchman keeps awake in vain.
Psalms 127:1 NASB
Have we placed our trust in the Lord, not just for our eternal life, but for how we live our daily life? God knows and wants to impact our day by day life as well. Do we acknowledge all that he does and is doing on our behalf? Unless He is the one who does it, it won’t last or be successful.
