Romans 11:32 (TPT)
‘Actually, God considers all of humanity to be prisoners of their unbelief, so that he can unlock our hearts and show his tender mercies to all who come to him.’
We are prisoners whenever we do not believe what He has promised us. We are held captive in bondage to that unbelief.
Let Him unlock your heart in that area you are struggling to trust Him in. It may look like it is too big for Him. It may even seem like a physical impossibility. But give Him your heart and watch Him unlock the truth and bring you back into faith.
The key is in your hands.
