Now, Israel, hear the decrees and laws I am about to teach you. Follow them so that you may live and may go in and take possession of the land the Lord, the God of your ancestors, is giving you. 2 Do not add to what I command you and do not subtract from it, but keep the commands of the Lord your God that I give you.
3 You saw with your own eyes what the Lord did at Baal Peor. The Lord your God destroyed from among you everyone who followed the Baal of Peor, 4 but all of you who held fast to the Lord your God are still alive today.
5 See, I have taught you decrees and laws as the Lord my God commanded me, so that you may follow them in the land you are entering to take possession of it. 6 Observe them carefully, for this will show your wisdom and understanding to the nations, who will hear about all these decrees and say, “Surely this great nation is a wise and understanding people.” 7 What other nation is so great as to have their gods near them the way the Lord our God is near us whenever we pray to him? 8 And what other nation is so great as to have such righteous decrees and laws as this body of laws I am setting before you today?
Romans 8:35, 37-39
35 Who shall separate us from the love of Christ? Shall trouble or hardship or persecution or famine or nakedness or danger or sword? … 37 No, in all these things we are more than conquerors through him who loved us. 38 For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, 39 neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
27 My sheep listen to my voice; I know them, and they follow me. 28 I give them eternal life, and they shall never perish; no one will snatch them out of my hand. 29 My Father, who has given them to me, is greater than all; no one can snatch them out of my Father’s hand.
John 15:5-6, 9-10
5 “I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing. 6 If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. … 9 “As the Father has loved me, so have I loved you. Now remain in my love. 10 If you keep my commands, you will remain in my love, just as I have kept my Father’s commands and remain in his love.
