God’s love for us is unreasonable – it is not based on reasons but merely on God’s sovereign decision. The resurrection of Jesus is also unreasonable in that it lies beyond the realm of reason either to prove or disprove. This is why it is the perfect demonstration of God’s unreasonable love. It is also why our unreasonable faith in the resurrection is the perfect human response to God’s unreasonable love.
God’s unconditional love does not imply that what we do doesn’t matter. Nor does believing that what we do matters imply that God’s love is conditional. The biblical truth is that God loves us unconditionally, and that is precisely why what we do matters.
To really know someone or something one must first love that someone or something. This applies both to human relationships and to Bible study.
