Ephesians 1:13-14 | NIV
13 And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit, 14 who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory.
13 …When you believed, you were marked in him with a seal, the promised Holy Spirit,
We need to KNOW who we are by the knowing whose we are. When we believed, we were marked in Him. We were marked in Him with the Holy Spirit. Therefore, we are His.
In this world where doubt and fear are present, we need to get this even more: we belong to Him.
We should pray like the Apostle prayed ever so constantly for the believers in Ephesians:
… that the God of our Lord Jesus Christ, the glorious Father, may give us the Spirit of wisdom and revelation, so that you may know him better (Ephesians 1:17)
… that the eyes of our heart may be enlightened in order that we may know the hope to which he has called us, the riches of his glorious inheritance in his holy people, (Ephesians 1:18)
… that the eyes of our heart may be enlightened that we may know his incomparably great power for us who believe. That power is the same mighty strength he exerted when he raised Christ from the dead and seated him at his right hand in the heavenly realms, (Ephesians 1:19-20)
We are marked. We are His. We belong to Him.
