There is none righteous, no, not one;
There is none who understands;
There is none who seeks after God.
They have all turned aside;
They have together become unprofitable;
There is none who does good, no, not one.
Their throat is an open tomb;
With their tongues they have practiced deceit;
The poison of asps is under their lips;
Whose mouth is full of cursing and bitterness.
Their feet are swift to shed blood;
Destruction and misery are in their ways;
And the way of peace they have not known.
There is no fear of God before their eyes. Rom 3:10-18

My sheep hear My voice, and I know them, and they follow Me. And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Fathers hand." John 10:24-29

And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent. I have glorified You on the earth. I have finished the work which You have given Me to do. And now, O Father, glorify Me together with Yourself, with the glory which I had with You before the world was. I have manifested Your name to the men whom You have given Me out of the world. They were Yours, You gave them to Me, and they have kept Your word. Now they have known that all things which You have given Me are from You. For I have given to them the words which You have given Me; and they have received them, and have known surely that I came forth from You; and they have believed that You sent Me. I pray for them. I do not pray for the world but for those whom You have given Me, for they are Yours. And all Mine are Yours, and Yours are Mine, and I am glorified in them. Now I am no longer in the world, but these are in the world, and I come to You. Holy Father, keep through Your name those whom You have given Me, that they may be one as We are...I do not pray for these alone, but also for those who will believe in Me through their word...Father, I desire that they also whom You gave Me may be with Me where I am, that they may behold My glory which You have given Me; for You loved Me before the foundation of the world. O righteous Father! The world has not known You, but I have known You; and these have known that You sent Me.
