Any attempt to live a holy life besides through God’s grace is your idea, your intellect, your own strength, your righteousness. In Isaiah 64:6 it says “…our righteousness is as filthy rags.” The word says in Romans 13:14 to “put ye on the Lord Jesus.” So we are to “lay off the old man “ Ephesians 4:22 and take on (Isaiah 61:10) the righteousness of God found in Christ. Our strength will doubtless fall short but God’s strength…God’s strength is unlimited. When you receive the Holy Ghost, God’s unlimited strength is within you. His grace is within you waiting to be activated by the release of your faith (Ephesians 2:8-9). Our ability cannot fulfill God’s standards but God’s ability is well able to fulfill the standards that God has set. According to the natural way that man(apart from God) thinks, you are to orient your life toward doing better works in order to be a better person. God’s way is that you spend time with Him and your heart is changed to where good works come naturally rather than fighting your will to do what you know is right. As you seek Him, He will change your heart and your life will change with it.
14 But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof.
22 That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
10 I will greatly rejoice in the Lord, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels.
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.
