When God's people become complacent they loose their strength in unity, closeness to God, and in wisdom. Complacent Christians become more like the world than the church that God designed for them. If you are a complacent Christians, then this is why you are not moving forward.
Complacency makes you susceptible to be more likely to do evil than good. You start doing what you think is right instead of what God said was right. It will lead to oppression and devastation in your life. God is not an idea that you have in your head. He is the once that created your head and everything else. He is seeking a close relationship with you, but if you choose yourself over Him then you will be the one missing out.
God's love for His people is boundless. His love for you is greater than you know. He provides mercy, strength, protection, and more while knowing where you are weak or unstable. Where you are struggling, God is trying to help. Will you let Him?
You need to understand, not just know, who God is and His character to be able to live passionately for Him. You trusting God and stepping out in faith can change everything in your life and the lives of the people around you. Live a complacent life and you are a slave to the whims of people in the world. You were not brought in this world to be a slave to anyone or anything. God is waiting to empower you, but you can't be complacent in your walk with Jesus or life.
God gives you what you need to be victorious in His name. You can't ignore or neglect God's commands and expect to be blessed. You have to be obedient even when you don't understand the command, afraid, or feel that it is unfair. God is justice. It will prevail in some way. Your calling may be intimidating, but running away will only make things worse. You may be an underdog, but if you have God supporting you then you can't lose. Ignore God in complacency and there is no end to all that could go wrong.
