A buttress is a projecting structure of wood or masonry that supports a wall or building. The broadened base of a tree is a kind of buttress to keep the tree from falling. Paul writes that those who belong to God are a pillar and buttress for the truth (1 Timothy 3:15).
People do not generally read the Bible, but they often read Christians. What knowledge are they gaining about God from observing your life (Hebrews 13:7-8)? Are contributing to the continuance of truth, or are the destruction of it in your world?
Ask God for the wisdom, boldness and strength you need. He will give it to you. Then walk and speak as God's representative.
