Ecclesiastes 11:4

He who watches the wind (waiting for all conditions to be perfect) will not sow (seed), and he who looks at the clouds will not reap (a harvest). 

When it comes to God’s leading, we are to react in Faith. Our minds will devise why we cannot when God says we can. Reasoning and fear will be a downfall, and we will miss out on blessings from God. Faith is now, and God’s promises require Faith to be achieved.
