We have all been frustrated or disappointed in someone or a circumstance. The sister of the man who died really believed if Jesus would have came when He was notified that Lazarus would still be alive.
On his arrival, Jesus found that Lazarus had already been in the tomb for four days. Now Bethany was less than two miles from Jerusalem, and many Jews had come to Martha and Mary to comfort them in the loss of their brother. When Martha heard that Jesus was coming, she went out to meet him, but Mary stayed at home. “Lord,” Martha said to Jesus, “if you had been here, my brother would not have died. But I know that even now God will give you whatever you ask.”
Jesus said to her, “Your brother will rise again.” Martha answered, “I know he will rise again in the resurrection at the last day.” Jesus said to her, “I am the resurrection and the life. The one who believes in me will live, even though they die; and whoever lives by believing in me will never die. Do you believe this?” “Yes, Lord,” she replied, “I believe that you are the Messiah, the Son of God,who is to come into the world.” - John 11:17-27
Martha had faith but she didn't have the experience or knowledge that Jesus has authority over life and death. There is much to be learned here. We cannot base God's supernatural power on our human understanding. Remember the song, "Trust and obey, for there's no other way to be happy in Jesus, but to..."
Praise God that we can grow in our faith and believe, "All things are possible in Christ"! Amen?
