Isaiah 40:8 (NKJV)
Snow can be like the different situations we face in life, something happens that completely changes how things look, but underneath nothing is really different. It may be one big that happens, or some little things that just seem to pile up, but it appears that everything has changed. For Christians, God's Word is our foundation and no matter what circumstance or change occurs, God's Word does not change and it must remain our foundation. If we are not careful, we can allow the different situations and problems we face in life to alter our perspective so that we forget what is reality and what it is that is just changing our view of it.
If we only see the problems and difficulties of life and forget about what we know from the Bible we can start living our life based on a false reality, this is why it is so important to have a good foundation of God's Word in our life. We need to be so familiar with the Word and so well versed in it that no matter what comes to try and cover things up we always remember our firm foundation of the Word. By knowing the truth of God's Word, we can always keep our focus on what the true reality is, no matter what happens and how things look on the surface. Circumstances come and go, but God's Word remains the same!
