Physical sickness and distressing circumstances can often affect our emotions, and it is possible to feel that God is far away. It is important, however, to realize that God loves you and is very close to you regardless of your feelings. In Jeremiah 31:3 we read, "I have loved you with an everlasting love; I have drawn you with loving-kindness."
If you have given your life to Christ, He is right there with you, regardless of the way you may feel. It is important that you trust God's Word about your relationship to Him. God has said, "So do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my righteous right hand" (Isaiah 41:10).
Take these wonderful promises, along with others in God's Word, and meditate on them until they become a part of your thinking. As the Lord gives you strength, spend time each day reading your Bible and praying. Do not worry about your temporary lack of feeling. God says in Hebrews 13:5b: "Never will I leave you; never will I forsake you." He is with you, and eventually your sense of His presence will return.
