Stumble
When we first started walking, we stumbled and fell every other step. With practice, our steps became more assured and now, as adults, we only stumble when an obstacle trips us. When the Bible speaks of stumbling, it is often referring to a sin that has been committed.

Although God has forgiven us, we still sin. The world, Satan and our paths that can cause us to lose our footing. We encounter even more of these obstacles when we leave the path that God has laid out for us in his Word. As we mature, however, we learn where the pitfalls are, and hopefully we stumble less.

The Bible calls obstacles that trip us "stumbling blocks." They can take many forms. Jesus was a stumbling stone to the religious people of his day. They simply could not believe that they, the descendants of Abraham, needed a Savior to forgive their sins. Even today, Jesus' teachings about himself pose an obstacle for those who cannot accept that Jesus Christ is the only way to God.

Things that may cause people to sin are described as stumbling blocks.

What may not be a stumbling block to you, may be a stumbling block to someone else. Make sure that your actions don't cause another Christian to sin.
