Why would God set such an impossible goal? We, by nature, are sinful. Ever since the fall of man in the garden of Eden, sin has been a core part of our beings. If God knows this, why then would He set such an unreachable standard?
The reason God has the standard of perfection, even though we cannot possibly reach it, is to show just how much we are in need of a Savior. It's shows His glory and lifts Him up.
B. God's saving grace.
Even though we are not perfect, there was one, and only one, man who was. His name was Jesus Christ, God's only Son. Because Jesus was perfect and knew no sin, He was able to die for your sins and mine and pay the penalty for sin, which is death (Romans 6:23).
Jesus stood where we belonged and took the full force of the hatred and wrath of God upon Himself. Not only did he just die a physical death, but he took all of God's anger, which we deserve, and took it upon Himself.
I want to make one thing very clear, it had nothing to do with us.
In his book, Radical, David Platt addresses a popular view on Christianity, he says, "If you were to ask the average Christian sitting in a worship service on Sunday morning to summarize the message of Christianity, You would most likely hear something along the lines of 'The message of Christianity is that God loves me.' Or someone might say, 'The message of Christianity is that God loves me enough to send His Son, Jesus, to die for me.' As wonderful as this sentiment sounds, is it biblical? Isn't it incomplete, based on what we have seen in the Bible? 'God loves me' is not the essence of biblical Christianity. Because if 'God loves me' is the message of Christianity, then who is the object of Christianity? God loves me. Me. Christianity's object is me... But that is not biblical Christianity. The message of Christianity is not 'God loves me, period,' as if we were the object of our own faith. The message of biblical Christianity is 'God loves me so that I might make Him—His ways, His salvation, His glory, and His greatness—known among all nations.' Now God is the object of our faith, and Christianity centers around Him. We are not the end of the gospel; God is."
So since when is the Gospel about me? It isn't. In Isaiah 48:9 God tells us, "For My name sake will I defer my anger, and for My praise I will withhold it from you, so that I will not cut you off." For His name sake and for His praise and glory, not ours.
That grace was by God, for God, so what we have to do is see His glory and accept His Son's sacrifice and praise Him because of our salvation. We have nothing to do with our salvation. It's not because we decided, "Oh, I will except God's gift because I don't want to go to Hell." No. If you are a Christian it is because God called you to Himself so that you would praise Him for eternity. Ephesians 2:8-9 says, "For by grace you are saved through faith; and it is not of yourselves: it is the gift of God: not of works, should any man boast."
So how does God see us after He saves us? How do we measure up to His standard?
When God looks on us, He no longer sees our sin. He sees our Savior, His Son, the Lord Jesus Christ. He looks at us, and this is what He sees: ‘The blood of Jesus, His Son, cleanses us from all sin’ (1 John 1:7). Through faith in Christ, we are sinners, saved by grace (Ephesians 2:8). This is the beauty the Lord sees in us: ‘There is, therefore, no condemnation for those who are in Christ Jesus’ (Romans 8:1). This is not our beauty. It’s His beauty!
But we cannot forget the second part of that verse, "Who walk not after the flesh, but after the Spirit."
Being a man after God's own heart doesn't end at salvation. We cannot think we can still live the way we did before God saved us, and still be a man of God. We need, as my third point states...
C. A shift in priorities.
We have read about our sin nature, and our hopelessness to meet God's standards. We've talked about God's grace, and the bridge He gave us to meet those standards. Now we will finish off by talking about the main point of the lesson. What is my heart's desire? Or, put another way, is your heart's desire to follow after God?
What we need is a radical change, or shift, in our priorities. What I mean by that is we need to have a change from physical, or worldly, things, to spiritual, or Godly, things. Like it says in Romans 8:1, "Who walk not after the flesh, but after the Spirit."
In Romans 12:2, the Bible says, "Do not be conformed to the ways of this world, but be transformed by the renewing of your mind." We need to do away with the things of this world and transform ourselves by renewing our mind. Ways we renew our mind are through prayer and the reading of God's word in deep study.
After we have made a change in our priorities, we then have to be obedient to the callings of God. let's look at more of Romans 12:2, "...So that you may prove what the will of God is."
We need to have a strong personal relationship with God so that we can know the heart and will of God.
What did God say about David? "...He will do all my will." So that means if we are to be men after God's own heart, we must humble ourselves, and act as vessels, and be obedient to the leading of God.
So, what has God been telling you to do? Are you being competely obedient? Do you have that strong relationship with God? Have you fully accepted the sacrifice of the Son? These are the things that lead us to be men after God's own heart.
