Have you ever wondered what best musical instrument will God accept ?The Bible says man looks at the outside but God looks at the inside, is it not ? So if God looks at us He sees our soul, mind and heart. If our heart is a musical instrument what tune does it play ? Only you and God can answer that. Is our heart's tune acceptable to God ?
Early in life i found that my heart is wicked , selfish and deceptive etc I found later in life that that was what Jeremiah the prophet wrote in the book that bear his name Jeremiah 17:9.. My heart's tune is totally unacceptable to God. So woe is me but God showed me a good news, God is in the business of changing heart/ hearts when we turnover our defective ones to Him.
Through Jesus Christ we can have a new heart and if our new heart is a musical instrument it can play music the way God loves it.
There is our answer, a new heart from God is the best musical instrument that God will accept.
