Being "Lutheran," our congregations accept and teach Bible-based teachings of Martin Luther that inspired the reformation of the Christian Church in the 16th century. The teaching of Luther and the reformers can be summarized in three short phrases: Grace alone, Faith alone, Scripture alone.The current church was built in 1954 and the hall attached to it was built in 1990. The hall often hosts the Red Cross blood drive.
God loves the people of the world, even though they are sinful, rebel against Him and do not deserve His love. He sent Jesus, His Son, to love the unlovable and save the ungodly.
By His suffering and death as the substitute for all people of all time, Jesus purchased and won forgiveness and eternal life for them. Those who hear this Good News and believe it have the eternal life that it offers. God creates faith in Christ and gives people forgiveness through Him.

Before the current church was built, the local congregation met for a number of years in a building on McKinley on the same city block as the Church of the Nazarene. This building now contains apartments and shows no external signs of ever having been used as a church.
The maps showing denominations from Valparaiso University (which is a Lutheran school) show that Lutheranism is strongest in the upper Midwest, from Wisconsin to Montana. In that area, the Missouri Synod is rarely the dominant Lutheran group, though it often is in the rest of the U.S. The Missouri Synod is important enough to have its own map. The Wikipedia entry on Lutheranism is here and its entry on the Missouri Synod is here.
