Unfailing love must be instilled by Jesus. In our own power, we are like Peter (denial)–or Judas (betrayal)!
Proverbs 20:6 Many a person claims to have unfailing love, but a faithful person who can find?
So, how do we lead blameless lives (v7)? The first thing we need to do is acknowledge the fact that we cannot please Jesus in our own power. In fact, we will always wind up pleasing ourselves. Isaiah said it very succinctly:
Isaiah 53:6 We all, like sheep, have gone astray, each of us has turned to his own way; and the LORD has laid on him the iniquity of us all.
Once we recognize that we are bankrupt spiritually (Matt. 5:3), we are ready to receive His love that is so freely given:
Romans 5:5 And hope does not disappoint us, because God has poured out his love into our hearts by the Holy Spirit, whom he has given us.
Now comes the hard part: We must put off the old person and put on the new person who is clothed in the righteousness of Christ.
Paul explains it like this:
Ephesians 4:17-24 (NLT) With the Lord’s authority let me say this: Live no longer as the ungodly do, for they are hopelessly confused [in the futility of their thinking].  Their closed minds are full of darkness [they want what the want]; they are far away from the life of God because they have shut their minds and hardened their hearts against him [they prefer to act according to how they feel].  They don’t care anymore about right and wrong, and they have given themselves over to immoral ways. Their lives are filled with all kinds of impurity and greed.
 But that isn’t what you were taught when you learned about Christ.  Since you have heard all about him and have learned the truth that is in Jesus [plus, we have received the Holy Spirit],  throw off your old evil nature and your former way of life, which is rotten through and through, full of lust and deception.  Instead, there must be a spiritual renewal of your thoughts and attitudes.  You must display a new nature because you are a new person, created in God’s likeness—righteous, holy, and true.
Let’s think about this:
- I can’t trust how I feel because my primal desires have been corrupted;
- I have Jesus living in/with me showing me the righteous way;
- All I need to do is die to self and live for Christ.
Easy peasy! 🤣 It’s a rigorous, life-long process that will not be completed this side of heaven (unless the LORD comes back!). But, we have these encouraging words and the promise that it will be worth it all:
1 Corinthians 15:57-58 But thanks be to God! He gives us the victory through our Lord Jesus Christ.
 Therefore, my dear brothers, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain.
Revelation 7:9-10 After this I looked and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and in front of the Lamb. They were wearing white robes and were holding palm branches in their hands.  And they cried out in a loud voice:
“Salvation belongs to our God, who sits on the throne, and to the Lamb.”
One glimpse of Jesus on His throne will make it all worthwhile! Let’s live in the knowledge of this hope today.
