“Strengthen the weak hands, and make firm the feeble knees. Say to those who have an anxious heart, “Be strong; fear not! Behold, your God will come with vengeance, with the recompense of God. He will come and save you.” – Isaiah 35:3-4 (ESV)
Through His prophets, God spoke to His people and gave them instruction and encouragement. He also warned them what would happen if they did not believe and the blessings for those who did believe. We have considered the promise of God that He is our eternal source of encouragement and today’s verse shows us a way we are encouraged. An anxious heart comes from fear. Fear comes from not trusting in God’s promises. These words are interesting because they mention feeble hands and knees that give way. But it is also clear that weak hands and shaky knees are caused by fearful hearts. So, what the Lord promises us is that He will come and He will strengthen our hearts so that we do not need to fear. When we trust him to help us not be afraid, that will make our hands and our knees strong. When we have needs like this in our lives our God is aware of them and He promises to come to help us. If we know that God will respond in this way, it encourages us to depend on Him and press on, whatever is ahead in our path.
