There is no fear in love [dread does not exist], but full-grown (complete, perfect) love turns fear out of doors and expels every trace of terror! For fear brings with it the thought of punishment, and [so] he who is afraid has not reached the full maturity of love [is not yet grown into love's complete perfection]. (1 John 4:18 AMP)
Understand when you have grown to MATURE LOVE, it's when you are not afraid, when there is no trace of terror, or thoughts of punishment. Understand this is when you have reached mature love! See our HEAVENLY FATHER reconciled within Himself that there would be NOTHING we could do that would cause HIM to stop loving us...and therefore we can be confident in HIS love. It's PERFECT towards us!
Now how does this translate to us? First you must understand that THIS IS A SPIRITUAL thing! In the "flesh" it's nearly impossible to incorporate this LOVE, because God is SPIRIT, therefore operating from your flesh does NOT include him. It becomes something you attempt to do on your own, and we know Jesus says that without Him we can do nothing.
So what's one to do?
Get in Christ! Let the Holy Spirit shed the Love of God abroad in our hearts, and operate from there! Do you understand that once you know what Gods will is for your life, in all areas...especially relationships, that there should be NO going back on that! Take up your cross (purpose) and walk! You can't just accept the best part of it, and think the enemy of your soul is not coming to cause chaos! As long as you are breathing you are a threat to him!
I have heard people who believe with all there heart that they were ordained by God, and the slightest hint of adversity and they begin to waver...and it's RIGHT THERE IN THAT MOMENT OF DOUBT, the enemy stuck his foot in the door you cracked open, and the mission to get you to walk away from your purpose just began!
Remember to just STAY in Christ! Let Him do the work, by You SPEAKING every word you Him say concerning your life! What God has determined for your life He will prepare you to hold if you allow Him. And trust the devil will do everything to convince you to walk away...even using love saying, you can't make them happy just walk away. Or you've accomplished so much, you don't need to do more. He may even whisper, you deserve to be happy, you deserve to do what you want that makes you happy, LOOK AT ALL YOU ACCOMPLISHED! Don't fall for his slick speech! Discern by the spirit what he is really saying in that moment! Cause you were never created to be responsible for someone else's HAPPINESS. That's not your job! You were not created to quit...you continue in Gods will til He says "well done my good and faithful servant!" You were BOUGHT with a price, therefore your life is HIS (Christ), and his plan goes far beyond your emotions!! And anytime you hear a whisper of someone telling you about ALL YOU have done(without any reference of Christ), rebuke the devil! Just as Jesus did to Peter when Peter rose up against what Jesus knew HAD TO HAPPEN.
Don't allow no man to tear asunder what God has brought together! I don't care what part of your destiny that relates too! Love is POWERFUL, because LOVE IS GOD!
