Build an altar of the Lord in my life

1 Kings 18:30-40
Elijah took twelve stones, one for each of the tribes from Jacob. With the stones he built an altar in around it large enough to hold two seahs of seed.
At the time of sacrifice, the prophet Elijah stepped forward and prayed: "O Lord, God of Abraham, Isaac and Israel, let it be know today that you are God in Israel and that I am your servant and have done all these things at your command. So these people will know that you, O Lord, are God and that you are turning their hearts back again."
When all the people saw this, they fell prostrate(拜倒) and cried, "The Lord - he is God! "
It's God who is 'the living Lord'. The fire burns the saturated offering. The people shout "The Lord alone is God.' The prophets of Baal are slaughtered.
Why?
Elijah first rebuilt the altar of God, for the altar is ruined. He want Israel build an altar, build the religious to the Lord. Recover the ruined faith to the Lord.
First built the heart of altar in my heart then God will listen our pray.
How?
To rebuild the altar what I need to do? Earnest to search God and made more closer to the Lord and listen to what he said to me.
