Faith

Now faith is being sure of what we hope for and certain of what we do not see. This is what the ancients were commended for. By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible.- Hebrews11:1-3
What does it mean to walk by faith? I believe that it is by believing the word of God and living our lives believing His promises, even though we don't see the evidence of them yet.  Faith is accepting as surety what is in God's Word.  What does he promise? In Matthew 6-25-34 Jesus promises that he knows the earthly things that we need; food, shelter, clothing, and he will provide these things for us as we need them.  He taught us to pray for our daily bread, not necessarily a full refrigerator. And walking by faith means much more than trusting that God will provide for our physical needs.  Most importantly, he provides for our spiritual needs. When we are walking in his will, we have fellowship with him through the Holy Spirit and are able to feel the love that he has for us.
When we walk by faith, we know when God is giving us opportunity to share the gospel with others.  He will put them in our path.
