2 Peter 1:4 says that through God’s exceedingly great and precious promises, we become partakers of His divine nature. Hebrews 1:3 says that the Son is the perfect imprint (Amplified) of the Father. We are created to exemplify the Lord ~ His image stamped deep into our hearts.
We certainly cannot represent Him in our own strength. The verse says, “Who being the brightness of His glory and the express image of His person, and upholding all things by the word of His power…”
Our faith is purified in the crucible of our trial. Through the intensity of the fire, the dross is brought to the surface and removed. Our ‘alloy’ of buried lies that we have believed are exposed. They lose their power of control when brought into the light. We then renounce them and affirm the truth. 2 Corinthians 4:2.
