Doing is believing.

 Psalm 8 NIV84

For the director of music. According to gittith. A psalm of David.

1 O LORD, our Lord, how majestic is your name in all the earth! You have set your glory above the heavens.
2 From the lips of children and infants you have ordained praise because of your enemies, to silence the foe and the avenger.
3 When I consider your heavens, the work of your fingers, the moon and the stars, which you have set in place,
4 what is man that you are mindful of him, the son of man that you care for him?
5 You made him a little lower than the heavenly beings and crowned him with glory and honor.
6 You made him ruler over the works of your hands; you put everything under his feet:
7 all flocks and herds, and the beasts of the field,
8 the birds of the air, and the fish of the sea, all that swim the paths of the seas.
9 O LORD, our Lord, how majestic is your name in all the earth!

Matthew 21:4-16 NKJV

Then the blind and the lame came to Him in the temple, and He healed them. 15 But when the chief priests and scribes saw the wonderful things that He did, and the children crying out in the temple and saying, “Hosanna to the Son of David!” they were indignant 16 and said to Him, “Do You hear what these are saying?” 

And Jesus said to them, “Yes. Have you never read,

‘Out of the mouth of babes and nursing infants 

You have perfected praise’?”

Jesus quoted this Scripture to the Pharisees to claim to them that the Scriptures were being fulfilled before their eyes.  He did not quote the latter half of the verse referring to silencing His enemies (the Pharisees) but because they were experts on the Scripture they would have known what the latter half of the verse said.  Jesus was witnessing to them that he is the Messiah and that they are God's enemies.  But, the Pharisees didn't believe the miracles Jesus' performed were from God, so how could they believe He was from God?  Jesus said that anyone who obeys His words will know whether He comes from God or not.  How about you?  Do you want to know whether Jesus comes from God?

When I buy something and it doesn't work I need to check to see if I followed the directions.  Our lives are like that.  God's Word the Bible gives me the directions I need to know so that I can know God the Father, God the Son (Jesus), and God the Holy Spirit.  Just reading the Bible however, without actually doing what it says to do, just puffs me up with pride, (the opposite of love).

But, reading and doing God's Word develops love in my heart.  Love for God.  And love for people.  When I help someone, like giving them a warm coat in the winter when they have none, or giving them food and schooling each day when they would otherwise go without... I am changed.  God changes me.  I feel a joy I've never known before.  The money I've spent on someone who needs it isn't a loss or expense. It's investing in them, investing in me, a gift given gratefully to God and investing in the joy we will all have in heaven.

So if you want to know Jesus, if you want to know if the Bible is true, then do what it says.  And Jesus will reveal Himself to you.
