Living faith
God produces faith in us by His Holy Spirit through the specific means of Word and the sacraments. That faith, just like anything that is living, needs to be sustained and kept alive. Thankfully for us, the same Spirit that produces faith also sustains it.
Walk this way
Paul points out to us that we should walk carefully because the days are evil, that understanding the Lord’s will for us will help us to walk on the right path, and that being filled with the Spirit will influence our walk of life in Christ.
Stick to His plan
All the apostles wanted was a quick fix—a political saviour who would restore Israel to its former glory. We aren't so different when we hope for instant solutions in the Church or in our personal lives. Christ calls His apostles (along with us) to a different way—a way of faith and witnessing.
Food, Faith & Freedom
Paul encourages the Corinthian Christians to use their knowledge of God and the Christian faith for the benefit of others and to build one another up in love. The specific example he speaks about is whether Christians should eat the food offered to idols, but the core issue underneath it all is how we are to live out the freedom we have in Christ.
