Romans 4:19

Without becoming weak in faith he considered his own body, now as good as dead (for producing children) since he was about a hundred years old, and (he considered the deadness of Sarah’s womb. But he did not doubt or waver in unbelief concerning the promise of God, but he grew strong and empowered by faith, giving glory to God. 

When it comes to faith and the situation, we should do our best only to consider God. If we focus on the circumstance, it will become more significant than the solution.   The solution is all that matters and not the problem, and the answer is God and His promises to us. Focus on the solution in faith and receive the promise as Abraham did.
