While, technically, there is a difference in the definition between missions and evangelism, (Evangelism is sharing the Word of God to those around you, in your community, state, or nation. Missions, on the other hand, are when you cross a different culture, i.e. learning a new language, studying the lifestyles and behaviors of a certain race.) to me, they are no different.
It's the approach and the strategy that is different, but the purpose is the same - to share the gospel that Jesus Christ is Lord and Savior, and our allegiance is only to Him.
Today's world is not just about geographical and regional cultures, but even family, workplace, and church cultures that a truly born-again Christian must cross to share about Jesus Christ. So yes, missions is no longer about partner or pioneer/frontier missions. Even in my front yard, I do missions.
Here's my experience. Though they may be tiny compared to some, I share it here anyway.
