Faith is being sure of what we hope for and certain of what we do not see. Hebrews 11:1

I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, 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. Romans 8:38-39

“Though the mountains be shaken and the hills be removed, yet my unfailing love for you will not be shaken nor my covenant of peace be removed,” says the LORD, who has compassion on you. Isaiah 54:10

Those who have served well gain an excellent standing and great assurance in their faith in Christ Jesus. 1 Timothy 3:13

Jesus said, “My sheep listen to my voice; I know them, and they follow me. I give them eternal life, and they shall never perish; no one can snatch them out of my hand. My Father, who has given them to me, is greater than all; no one can snatch them out of my Father’s hand.” John 10:27-29

I am not ashamed, because I know whom I have believed, and am convinced that he is able to guard what I have entrusted to him for that day. 2 Timothy 1:12

Brothers, since we have confidence to enter the Most Holy Place by the blood of Jesus…let us draw near to God with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water. Hebrews 10:19, 22
