Overcome means to conquer, to have victory over, to gain mastery over. Everyone who is Born of God, overcomes. Jesus, is our Model who had mastery over the world, the flesh and the devil.
God has also permitted us believers to journey through a world where we will face trials and tribulations (adverse situations). These could be caused by the devil, by the actions of other people or sometimes as a result of our own choices. The devil's attacks are an attempt to steal, kill or destroy what is ours.
However, God empowers us to overcome. Each victory we win puts us in a place of greater spiritual strength.
Our Lust for evil things… idolatry… sexual impurity… rebellion… is what keeps us away from moving into the Promised Land that God has called us into… We end up wandering in circles in the wilderness of bondages & strongholds… It is now time for us to wake up to our calling and pursue the march of victory into our spiritual inheritance.
