God WILL fulfill His purpose for our lives by His grace (even when it seems the journey isn't going anywhere, or is too difficult for us to handle in our own strength). Depend on Him alone to do it. He loves us... Jesus died to prove it.
God's Word gives us Endurance and Encouragement to "remain under" the challenges He allots in our lives. https://www.youtube.com/watch?v=DXBphYRZGCs&t=2s
Our God reigns - even in our suffering, when it seems His power is concealed - and He will deliver us! https://www.youtube.com/watch?v=iVytsrh-DhQ&t=9s
Knowing that God is sympathetic toward our suffering - and that He will bring us relief - helps us to be patient through it all. https://www.youtube.com/watch?v=jZrVxb151Oc
