Co-heirs with Christ

"So you are no longer a slave, but a son; and since you are a son, God has made you also an heir."
- Galatians 4:7

God only does what is right, and what is best for us. Instead if questioning God, our attitude should be like this:
"I don't know what You're doing, Lord, but I know this:
You are a God of justice, of faithfulness, of holiness, of purity, of power and of right judgment.
I bow before Your superior knowledge and wisdom and ask for grace to bear Your discipline."

This should be our teachability.

"Unless the LORD builds the house,
its builders labor in vain.
Unless the LORD watches over the city,
the watchmen stand guard in vain."
- Psalm 127:1
