Many of us don't know and understand the love God has for us, so it's hard for us to be completely dependent on Him. First John 4:16 says, "And we have known and believed the love God has for us. God is love, and he who abides in love abides in God, and God in him" (NKJV).
We know God loves us because He tells us so. And, we know by His actions. He sent His only Son to suffer and die in order to take away our sins and provide us with eternal life so we could be with Him forever.
Many of us intellectually know that God loves us. But do we really believe He loves us? Do we claim all that He has for us?
Knowing and believing are two separate things. If we believe God loves us, we have no cause to worry about anything. He is the only one who will never let us down. There is no one like Him.
Many times we feel we don't deserve God's love, but it's not about what we do to earn His love. It's about what He did for us--He gave.
What matters to God is that we learn to accept His love as freely given to us. God's love makes it possible for us to work through any situation that comes our way.
