God wants us to get in the habit of running to Him for grace (supernatural inner strength). He wants us to rely solely on Him.
But the enemy tries to lie to us, telling us that we're not good enough to be in God's presence. Satan tries to convince us that we've made too many mistakes for God to want to have anything to do with us.
But that's not what God's Word says. His Word says that as His redeemed and forgiven children, we can boldly approach His throne. You need to receive this truth today and make the choice to live by it.
Instead of saying, "I don't feel like God loves me," "I don't feel like I'm forgiven" or "I don't feel like I have a future," say, "God loves me, and nothing can separate me from His love. He has forgiven me and I can approach Him right now with confidence that He accepts me."
Every time you feel unworthy, remember what the Word of God says, and then boldly go to your heavenly Father. He is waiting eagerly to receive you.
