For us to be nailed to the cross with Christ, it is a requirement from God that our faith be complete.
The process is simple unless it is a religion you are in - in that case there are tons of work to be done...
The process is simple too.
1) we hear the message of Christ - the gospel of our salvation in Him
2) we believe the message from our hearts
3) we were sealed with the Holy Spirit
( Jesus said in John 14:16 that the Holy Spirit will be with us and in us forever - now was Jesus lying or is he like a "bait and switch" car salesman that has "fine print" which He doesn't talk about )
Ephesians 1:13 (NASB)
[SUP]13 [/SUP] In Him, you also, after listening to the message of truth, = 1) the gospel of your salvation—having also believed, = 2) you were sealed in Him with the Holy Spirit of promise, = 3)
you were sealed = aorist indicative tense / passive voice = a one time event in the past.
Passive voice = the sealing was not done by us but by an outside force - the Holy Spirit Himself.
