Something just occurred to me.
People sometimes look at their circumstances and wonder if God really cares. If God cared, He would do something about it, right?
Scripture says of Jesus, "For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin."
So did Jesus wrestle with doubt and wonder if God cared about him? In Luke 4:9-12, we see Jesus facing this very temptation. Satan, in a series of temptations, took Jesus to the pinnacle of the temple in Jerusalem and said, "'If you are the Son of God, throw yourself down from here, for it is written, "He will command his angels concerning you, to guard you," and, "On their hands they will bear you up, lest you strike your foot against a stone." And Jesus answered him, 'It is said, "You shall not put the Lord your God to the test."'"
My friend John put this into context for me last week. This is just like when we say, "God, if you really loved me, my wife wouldn't have this brain tumor." Or, "God, if you really love me, I won't be single into my thirties."
God understands our struggle and our circumstances. Jesus confronted questions just like ours. But Jesus didn't doubt God's love for him. He knew he didn't need to test it. We can also have assurance of God's love in what Jesus did for us. He already offered us salvation. What else does He have to prove?
