"...when I was sent for, I came without raising any objection." Acts 10:29.
Do you ever find yourself being called on by God to do something way out of your comfort zone? Do you go for it, fear and all? Or, do you hesitate, and find ways to talk yourself out of what God has put on your heart to do?
Obedience is one element of love. As husbands, we obey our vows to our wives, we obey our commitments as fathers. With God, it is being available to Him to be used where you are right now to share the news of Jesus Christ with the people around you. The question remains, how do you respond to God when He calls on you to act? Do you go without hesitation like Peter in Acts 10, or do you cling on to your worldly comfort zone like the rich man in Matthew 19:16-30.
I am not saying that obeying God is always easy either. That's the part where we are taken out of our comfort zones. As Christians sharing the news of Jesus with the world, we are asked to do crazy things like walk on water, feed thousands of people with 7 loaves of bread and some fish, continue to teach about Jesus under threat of death, or talk with our neighbors while watering the front yard and inviting them to church.
In the context of Peter in Acts 10, the church has been dispersed after the death of Stephen (Acts 8:1-3) and the Sanhedrin is trying to kill the apostles while dragging believers to prison. One day, 2 random men show up and say come with us to see our boss. You'll like him. He's a Roman centurion. When most people would have the common sense to run, Peter goes with the men to see the centurion because he chooses to be obedient to what God had already shown him. The result of this meeting is that now God's salvation is available to anyone who will believe. It ceased to be an Israel-only thing. We would not have that kind of salvation if it weren't for Peter's willingness to go where God led him.
God can use you in a very big way as well, and probably has already put on your heart what you need to do. Take that step of faith wanting glory for no one but God, and you may be amazed by what comes of it. Go without raising any objection.
