 In Christianity, Jesus is the central figure of worship, believed to be the Son of God and the Savior of humanity. And God as well, as the graphic here in the background shows, Christians worship Jesus. By saying he wasn't just a man, he was fully man and fully God. This is how Christians justify to worship a man and not discard it as paganism. However, if we look into the tradition of Judaism that Christianity is based upon, we can of course see in the Old Testament, that God most certainly is not a man. It says it clearly in the Old Testament. And this is why just by this graphic alone you can see that the Jews and the Muslims are worshiping basically the one God with certain different conceptions. However, the Christians in the middle are most certainly not worshiping the same God because their God is Trinitarian in nature and moreover he manifests himself in the man Jesus.
