He meant all men are fallen and every day we battle our "old man" who still wants to sin by yielding to temptation. It's not easy to trust God 24/7 with all our whole heart. But that is the commandment and that is what we strive to do. If we are indwelled by the Holy Spirit, we will be able to trust in God to the saving of our souls. If not, we won't want to bother.
Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin... For sin shall not have dominion over you: for ye are not under the law, but under grace... Being then made free from sin, ye became the servants of righteousness." -- Romans 6:5-6,14,18"For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
How are we "made free from sin" when we still sin every day, as John reminded us in 1 John 1:8?
By Christ dying in our place and taking on the punishment rightly due us so that we now stand before God acquitted of our sins by the faith, obedience and righteousness of Jesus Christ mercifully imputed to us.
"Be not afraid; only believe." We can both agree on that!! Although we may place what it means to us a little differently.
Where do you place it?
And as long as we live we will battle our basic human nature,I believe that in the fullness of time Jesus came to help us find our way back to the Father who created us and desires we all find our way back. While He walked the earth He showed and told us what to expect and how we should act.
I believe Him when He said "I am the Way,the Truth and the Life".Many days,weeks and sometimes even longer ,I forget the Way He walked and stray from the path that allows me to do what He asked,which was to "follow me".
So to answer your question,which was where I placed it,the answer is I place it where it belongs when I get over me and follow Him.
