Invite (all) to the Way of thy Lord with wisdom and beautiful preaching; and reason with them in ways that are best and most gracious: for thy Lord knoweth best, who have strayed from His Path, and who receive guidance. Qur'an - 16:125 (Y. Ali)
No doubt it is a good idea to indulge in beautiful preaching or as Bro. Keith would prefer, sermons. That said when it comes to faith and religion, truth is extremely essential.
It is He Who has sent His Messenger with Guidance and the Religion of Truth, to proclaim it over all religion: and enough is Allah for a Witness. Qur'an - 48:28 (Y. Ali)
Unfortunately Bro. Keith seems to not know why the unconditionally loving Father made that sandbox for his children or he is just avoiding it because he knows that it contradicts his entrapping sermon that the Father loves us unconditionally.
Like in all the other situations, eventually I will have to clarify why God made that sandbox and the true ways of God. Those answers cannot be found in the Bible because the Bible is flawed. Especially the New Testament.
