John 8:9; And they which heard it being convicted by their own conscience went out one by one, beginning at the eldest even unto the last, and Jesus was left alone and the woman standing in the midst.
All have sin and fallen short of the Glory of God, we therefore live a life in search of absorption and redemption. As Christians we are made righteous by our faith in Christ and by our work we can call ourselves sons and daughters of God for we have believed and have been redeemed by the precious blood of Christ that flowed on the cross of Calvary. However, this does not give us the authorization to condemn others as some of our fellow are found of doing.
The great commission was for us as Christians to step out in to the world and search for souls that need saving, that they may be brought to Christ and that they may be redeemed as we were redeemed, so they may come know and believe in Christ and live a life of righteousness. If Christ Jesus did not condemn us irrespective of our sinful nature who are we to condemn others? May the good Lord strengthen that we may be able to do his work and bring others into the light of his knowledge and salvation, Have great Day.
