Encore Post: Evangelicals reject infant baptism is they think faith is all about understanding and agreeing to a series of teachings about God, Jesus in particular, and how we are saved. Since infants and young children have little ability to understand things intellectually. For Lutherans and the Holy Scriptures, faith is not an exercise of our reason, but a trust in God’s promises.
The problem with understanding faith this way is that even adults do not always have an ability to think, and, when they do, may still reject the Gospel. Lutheran theologians point out that we do not think when we sleep or in a coma. Sometimes disease can take from us our mind in old age or brain trauma. Yet such adults are not considered by anyone to have lost their faith.
On the contrary, Jesus and the Apostles tell us children do have faith. In fact, Jesus praises their ability to trust God. (Matthew 18:2-6, Mark 10:13-16) John the Baptist and Timothy believed in the womb (Luke 1:41-44, 2 Timothy 3:15) So, faith is all about trusting in God to save us and children are the most trusting of all people. Jesus does not urge children to become more like adults when it comes to faith. He urges adults to become more like children.
