Keep your faith pure

"Then I went down to the potter's house, and there he was, making something at the wheel. And the vessel that he made of clay was marred in the hand of the potter; so he made it again into another vessel, as it seemed good to the potter to make. Then the word of the LORD came to me, saying: “O house of Israel, can I not do with you as this potter?" Jeremiah 18.3-6
Meditating on the fact that the vessel was marred in the "hands" of the Potter (God), I understand that the only thing that limits His power is our free will.
One of the biggest obstacles that has hindered the fulfillment of God's purpose in the past generations is the idea, which has become increasingly global, that "we have the right to do whatever pleases us, and it’s nobody's business." Those who have this attitude towards others will inevitably have the same attitude towards God.
In fact, haven’t we treated Him like this sometimes?
When we are young and our faith is "pure”, we think that we have a clear picture of what God wants to do with us and through us. Now that we are older, we realize how far we are from this, and it's all our fault. God has not able to do for us and through us what He "wanted and had planned" because we have resisted His power and allowed other influences to shape us into something much less useful and valuable. Certainly, the altar is where we should keep our "free will". In other words, this is where we should SACRIFICE it.
But there is still hope for those who "want" to be molded by God, regardless of how long they have resisted Him. Saul of Tarsus was a marred vessel while he resisted the power of the Word of God and "kicked against the goads*", but when he asked trembling, "Lord, what do You want me to do?" God turned him into a vessel of honor.
No matter how rotten our lives are, or how long they have been this way, if we "want" this change with ALL our being and strength, God will do this in our lives.
God bless you.
*A goad was a long metal rod with a sharp pointed end, which was used to cause discomfort and pain to animals, making them obey their owner. It was only used on stubborn and obstinate animals.
