English Standard Version
Christians are supposed to be like Christ. It really begins by putting aside Earthly problems and focusing in on the fundamentals of Christianity and of course that means Christ. It involves our thinking and our practical application (verses 8 and 9) and is motivated by love (verse 1). Just like the reflection in the water really shows what the mountain is like, so we need to reveal our spiritual father. This is Paul's point and he could make it well because he lived it; Do we? Reflect on this and grow in grace and truth.
