The Five Points of Calvinism (TULIP) are not all there is to the gospel. They are certainly not all there is to the doctrine of gospel election, either. They put election in a box; low-grace infralapsarians claim to believe them as much as high-grace supralapsarians.
Men put a lot of God's truth in a box. In the end, the WHOLE of scripture is our judge. ... The arena of revealed truth is simple yet massive; no man can learn it all in this life. The mature aspects of it that we learn late in our Christian walk are just as critical as the simple aspects; the 'meat' is no less important in God's estimation than the 'milk.' It is all given in God's own time to his regenerate children.
