"And you shall seek me and find me, when you shall search for me with all your heart."  Jeremiah 29:13.  People who want to believe that there are many paths to God will say, "What about the people that live in the deep dark regions of Africa, or on unexplored islands, etc. who have never heard about Jesus?  You can't expect them to know what to do."  But consider this: The Ethiopian had never heard about Jesus.  He was living in Africa.  And when Phillip appeared and witnessed to him, the Ethiopian was traveling through Gaza, a desert.  The middle of nowhere.

God is in the business of rewarding those who seek him by giving them answers. We are just the vehicle that he uses--if we are willing.  Phillip could have questioned God.  He could have said, "Lord, I'm busy here in Samaria and thousands are coming to saving faith in Christ.  I'm sure you've made a mistake and don't really want me to just jump up and go to Gaza."

But Phillip didn't say that.  He did what God asked him to do.  If everyone does what God asks them to do, the world will hear the good news.  One person at a time.  However, we know that there are some who will refuse to listen.  Paul said it this way: "For the invisible things of Him from the creation of the world are clearly seen...even his eternal power and Godhead; so that they are without excuse...Romans 1:20.  There are those who will refuse to listen to God's voice.

Each individual--everyone everywhere--is accountable.  Because: "The heavens declare the glory of God; and the skies show his handiwork.  Day unto day they utter speech, and night unto night show knowledge.  There is no speech nor language, where their voice is not heard.  Psalm 19:1-3

Having seen God's work in the heavens, and the earth, the next step for each person is to seek answers.  And God promises to provide them.  If you seek Him, you will find him.  You will.

Four steps.  1.  Believe that there is a God.  A creator.   2.  Respond.  (This is where God has promised to come in and reveal himself.)   3. Repent and acknowledge that Jesus has paid your debt for sin.  4.  Trust Him.  With your life, your mind and your future.  That's it.  What is really neat is that God says that he will come and live within you and direct your paths.  That is the Holy Spirit.  "Christ in you, the hope of glory."  Colossians 1:27  What a deal.
