"For we walk by faith, not by sight."
2 Corinthians 5:7 (NKJV)
Faith is a key element in the Christian life. We are saved by grace through faith (Ephesians 2:8), without faith we cannot please God (Hebrews 11:6), the just shall live by faith (Galatians 3:11), and we walk by faith not sight (2 Corinthians 5:7). All of this talks about faith, which comes from God's Word (Romans 10:17) and is not based on what we see (Hebrews 11:1). From this we learn that we are saved, we please God, and we live by God's Word and not by what we see.
Too often, instead of taking a stand in faith on what God has said in His Word, we are looking around for some natural evidence that will help us locate ourselves in what we dealing with. But, with anything we are facing in life, from the point of our salvation onward, we need to put our confidence and trust in God and relax in our faith knowing that God's Word is true and He is faithful to do what He has said He will do. Take your stand in faith on God's Word and don't bother "looking out the windows", there is nothing we need to see out there.
