Do not let anyone try to bring condemnation on you.
"For God sent not His Son into the world to condemn the world; but that the world through Him might be saved. He that believeth on him is not condemned; but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. "John 3:17, 18.
The devil is good at trying to belittle the work of God in our lives, also in bringing up past shortcomings and sins. What God has done is on God, we do not need to defend God, or justify what He has done. God can take care of Himself. And past sins, when we have asked for forgiveness, are put into the 'sea of forgetfulness', it is as if it had never happened.
If we believe in God, believe in His Word, and believe in the Name of His only Son, then we are not condemned, and no one can bring condemnation on us.
"No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD." Isaiah 54:17
We depend on God's righteousness. And so there can be no condemnation from others.
