The Validating Sign

I think the first time God uses signs to validate His messenger and His message is in Exodus 4 with Moses. Moses is commissioned by God to go and speak to His people, but Moses is afraid that the people won't listen; that they will not recognize Him as a "sent one" and thus will reject his message. (Now before we are too hard on Moses for his fear remember how he had tried earlier to get the people to follow him - Exodus 2:15).
As a solution to Moses' objections, God provides Moses with three signs: 1. When he throws his staff down it turns into a snake 2. When he puts his hand into his cloak and brings it out...it comes out leprous 3. When he pours water from the Nile it turns into blood. Three signs, all designated to affirm to the people that God had visited His people, that Moses is indeed God's "sent one" and that his message ought to be heeded.
Fast forward now to the time of Christ. In Luke 7 Jesus comes upon a man who is dead. Having compassion on the widow of this man, Jesus performs a miracle raising this man from the dead. And what is the response of those who see this sign? They declare that "a prophet has risen among us" and "God has visited His people!" The sign validated God's "Sent One" and commends them to give heed to His words.
Later in the same chapter, John the Baptist sends some of his disciples to Jesus with a question. Is He the One who is to come (the Sent One) or should they look for another? And what is Jesus' response to them? It appears He first performs many miracles (signs) and then sends John's disciples away instructing them to tell John what they saw. Again, the signs seem to validate Jesus' person, that He is the "Sent One" of God, that God had indeed visited His people.
What about today? Is God validating His messengers (us) in any way? Is there anything that we might display that will convince our auditors that we have been sent by God and that our message needs to be heeded? I think our reading in 1 Cor 8 gives one very important sign and that is the sign of "love". When others see that we love the "weak" of which Paul speaks in 1 Cor 8; when others see the love of God for the afflicted and needy flowing through us, then they will conclude that God has visited us, that a prophet is among them, that our message is worth listening to.
Jesus Himself said, "By this all men will know that you are My disciples, if you love one another." Love really is the validating sign, actually showing that the "Sent One" lives within us, and wants to speaks His life giving message through us. May the Lord help us all this day to validate our God-given message with the uncommon love of Christ!
