Trust in the promises of the Lord and look to Him when you are weary. At times it may seem as though God is not present but these are the times when He wants us to practice patience and seek Him even more.
"The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance." - 2 Peter 3:9
