I can't share much of his testimony because it will endanger his life as he is sharing his faith in a nation where persecution is very real.
One thing that's very consistent in his life and his testimony is the importance of reading God's word and praying in a daily basis.
With this 2 basis, he can endure the hardship and show the love of Christ to multitudes.
It's just so simple.
His sharing was very simple yet it's so powerful. It involved lots of sacrifice, yet through his life testimony, it's very possible.
He is such a simple man that God use him to prove that doing God's will doesn't require great skills, great revival, even great vision. Yes, all these are important, but God can use us regardless of our ability and circumstances.
It's just about a willing heart and obedience.
God prefer obedience more that sacrifice.
1 Samuel 15:22 (New International Version)
22 But Samuel replied:
"Does the LORD delight in burnt offerings and sacrifices
as much as in obeying the voice of the LORD ?
To obey is better than sacrifice,
and to heed is better than the fat of rams.
