Those who belong to Christ Jesus have nailed the passions and desires of their sinful nature to His cross and crucified them there.
Since we are living by the Spirit, let us follow the Spirit's leading in every part of our lives.-----Galatians 5:24-25
I believe that this would be what we call being "SOLD-OUT" to Jesus Christ, when a person has TRULY ACCEPTED the fact that Jesus died for them, with ALL their HEART and NOT just in their minds, then they REPENT of their sins and nail them to the old rugged cross, to be crucified with Christ and to be covered by His precious blood.
Then we become a NEW creature and ALL our old ways have passed away and we become BRAND NEW, just like a new born babe. The Holy Spirit of the Living God indwells us and we begin our NEW life by allowing the Spirit to guide us down the path that our Heavenly Father has planned for us to take. Thus we MUST follow the leadership of the Spirit in EVERY PART of our lives, NOT just the parts that we want to allow Him to lead us, but in EVERY PART. He must have COMPLETE CONTROL! When we open EVERY PART to His leadership then we are living a "SPIRIT-FILLED" life, because He is in EVERY PART of our lives.
If you haven't nailed the passions and desires of your sinful nature to the old rugged cross, you can do it NOW by: CONFESSING your sins to God and asking for His FORGIVENESS, BELIEVING with ALL your HEART that Jesus died for YOU and is ALIVE making intercession for you before God, then ACCEPT His gift of SALVATION and FOLLOW the SPIRIT'S leading in EVERY PART of YOUR life. Do it NOW, while you STILL can. He's waiting!!
