The world seems to be running a muck and is a dangerous place. As Believers it is good to know that all who belong to the Father are secure in Christ Jesus!
1 John: 5:12 speaks of security,
"He who has the Son has life..."
And,
Vs. 13 speaks of assurance,
"...you may know that you have eternal life."

Security and assurance! Scripture has much to say concerning this.
Hopefully, the verses mentioned here will cause each of us to do a further study so that as Believers there is no doubt of our safe place in God.

Our security is expressed in words as seen in the following three verses:
'...they shall never perish...' Jesus speaking in John 10:28, "And I give they eternal life, and they shall never perish; neither can anyone snatch them out of My hand."

'...none of them is lost...' Jesus speaking to His Father in John 17:12, "While I was with them in the world, I kept them in Your name. Those whom You gave Me I have kept, and none of them is lost except the son of perdition, that the Scripture might be fulfilled."

'...kept by the power of God...' 1 Peter 1:5, "Who are kept by the power of God through faith for salvation ready to be revealed in the last time."

Our security is guaranteed--
By the Spirit's sealing:
Paul speaking in 2 Corinthians 1:21-22,
"Now He who establishes us with you in Christ and has anointed us is God, who also has sealed us and given us the Spirit in our hearts as a deposit."

By Christ's intercession: (Read Romans 8: 34-39 and rejoice!) "For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, nor height nor depth, nor any other created things, shall be able to separate us from the love of God which is in Christ Jesus our Lord." Vs. 38-39

By God's power:
"Now to Him who is able to keep you from stumbling, and to present you faultless before the presence of His glory with exceeding joy, to our God and our Savior, who alone is wise be glory and majesty, dominion and power, both now and forever. Amen." Jude 24-25

Assurance (the state of being assured; freedom from doubt and uncertainty).
Scripture speaks of bearing witness to the Spiritual adoption of Believers:
"The Spirit Himself bears witness with our spirit that we are children of God." Romans 8:16

"And because you are sons, God has sent forth the Spirit of His Son into your hearts, crying out, 'Abba, Father!'" Galatians 4:6

"Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit whom He has given us."
1 John 3:24

"By this we know that we abide in Him, and He in us, because He has given us of His Spirit." 1 John 4:13

Knowing our security and assurance is fully sure in God's salvation, Believers walk confidently in His love, "And walk in love, as Christ also has loved us and given Himself for us."
Ephesians 5:2
Let it be so with us,
"...because as He is, so are we in this world." 1 John 4:17

So we sing:
"Praise God from Whom all blessings flow, Praise Him all creatures here below, Praise Him above ye heavenly host, Praise Father, Son and Holy Ghost. Amen."

All praise, honor and glory to you Most Holy Mighty God. Amen
