A heart in living day to day can become cold and silent. We don't hear, or see, or feel. We have our compassion dulled, and our love for God gets kind of lukewarm. The worst hardness is a stony heart. Many times it comes from being broken or used. We shut down and even become callous. We need to stir up the zeal for the Lord so that the Holy Spirit blazes within our hearts, a heart with zeal. That's the way our hearts are no longer stony but hearts of flesh.
Our days call for wisdom we don't have. There are so many decisions, people to love, people difficult to love, people to forgive. As we stir up the zeal for our Savior we'll be more sensitive and willing to do what He writes on our hearts to do.
(2 Timothy 1:6) Timothy, Paul's spiritual son in the Bible, needed to stir up the gift within him. He had grown dull of heart and lost his brave spirit. Paul told Timothy to remember his faith from the past. It was strong and courageous and blazing. And it was when he was fully, completely, with all his heart depending on Jesus.
As the New Year comes it's a good time to refresh our faith. We need to, most importantly, depend, lean on Jesus with all we have. We need to be brave and blazing with a love for our Savior.
Never lag in zeal and in earnest endeavor; be aglow and burning with the Spirit, serving the Lord. (Romans 12:11 AMP)
And I will give them one heart [a new heart] and I will put a new spirit within them; and I will take the stony [unnaturally hardened] heart out of their flesh, and will give them a heart of flesh [sensitive and responsive to the touch of their God], [Ezek. 18:31; 36:26; II Cor. 3:3.] (Ezekiel 11:19 AMP)
