"A pure heart" - this is what we don't have. This is what we need - a change of heart. This is something we can't do for ourselves. It needs to be done for us - by God, our Creator. We need a new creation. This is what God has given to us in Jesus Christ (2 Corinthians 5:17). Often, we fail to live in the power of Christ. We revert back to living in the weakness of the flesh. We read, in this prayer, about "a steadfast spirit." We say, "This is what we need." God says, "This is what I've already given to you." He says to us, "You are a new creation in Christ. This is what I have made you. I have given you new life in Christ. Live the life that you have been given."
2 Samuel 7:1-29 Life isn't easy. Sometimes, it seems like there are nothing but hard times. There doesn't seem to be alight at the end of the tunnel. That's the way it feels - but it's not the way it is! Our feelings will lead us away from You - if we let them! Our feelings can run riot over us. They can wreck our lives. Help us, Lord, to look beyond the chaos. Help us to look to You. Sometimes, it feels like You're far away. That's the way it seems to us - but it's not the way it really is! You are with us - now and always (Matthew 1:23; Matthew 28:20).
