I have a different view. I Pastor once told me we get longsuffering by suffering long. On the surface it seemed right but I felt as if I heard God whispering in my spirit this- Longsuffering is a fruit of the Spirit and is manifest as we abide in the Vine.
God has placed a new man inside of us, this spirit man is pure of heart:
1Jn 5:18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
As far as our thinking we are told to think on things of good report, transformed by the renewing of our mind and to be renewed in the spirit (or life force) of our mind.
This mind, will emotions,intellect or soul is what Jesus came to save. We are renewed as our thoughts line up with the Word of God by the power of His Spirit which again is accomplished as we abide in this heavenly Vine:
Tit 3:5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
It can certainly seem hard to surrender and let His Spirit lead us in life but that for the most part is a deception of the flesh (at least it is in my case). Things I have struggled with that seemed so impossible to let go of and be free from seem unimportant when I view them in my rear view mirror. In my thoughts it seemed impossible but in reality all things are possible with God. If things seem to difficult we may find that we are pulling ahead of or lagging behind the Master as His yoke is easy and His burden light.
Apologies for rambling- these are just some of my experiences and I know each one of our walks is unique. Thanks for getting me thinking!
Much love in Christ, brother Larry.
