There are many things in our life that seem impossible to us. And, for us, there really ARE a lot of impossible things. But nothing is impossible for God. If we want God to open a “door” for us, we should knock! The most important “locked door” is the door to heaven. There’s nothing that we can do in our own power to gain eternal life, It’s only through belief in Jesus Christ. And if you do believe in Jesus, the doors to heaven are opened for you. And though God can open any door He wants, He allows us to keep the door to our hearts locked if we choose to. He’s knocking on the door of your heart, asking to come in. But the choice is up to you. And God won’t open every door for you, some doors He keeps closed. Some opportunities seem good but aren’t as good as what God has planned for you. But you can trust that, if you are walking with God, the right doors will always be opened for you if you simply knock.
