2 Peter 2:19
"They promise them freedom, while they themselves are slaves of depravity, for, people are slaves to whatever has mastered them." NIV
"While they promise them liberty, they themselves are the servants of corruption: for of whom a man is overcome, of the same is he brought in bondage."KJV
It's for sure that most of us would deny that we are mastered by anything but God and ourselves. But if we take a much deeper look inside and let the Holy Spirit reveal truth to us, we will find that there are other masters lurking within us that we refuse to admit. Many things overcome us, or render us weak to deny and we give in to them. This means those things are our masters. It could be our families, our possessions, our jobs, our talents, or hobbies. If we do not have full control over them and God is not above them, we are slaves to them. God says we will have no other gods before Him. If we ask Him to search our hearts and get rid of those things that make us slaves, we will be slaves to God only and serve Him with joy and peace.
Heavenly Father, we ask that the Holy Spirit would reveal to us if there are masters other than God within our hearts and lives. If there are, help us by the power of the Holy Spirit and our faith to get rid of those things so that they no longer have control over our lives. We ask this in Jesus' name, Amen.
