In Christ you have a guarantee. Before addressing spiritual warfare and marriage and family life God gives a guarantee to His people in the first chapter of Ephesians, The Holy Spirit. Paul tells us here that we have an inheritance coming to us which is total and complete redemption. One day, in the next life, we will be in the presence of God and He will make us just like Jesus. We will be holy, pure and, blameless.
Until that day God gives us His Spirit which is the mark of Salvation. Everyone who is saved has The Holy Spirit. Do you ever have times where you feel alone? Well in Christ you never are alone! Christ has promised His Spirit to you that will be a Comforter, Helper, Guide, and Friend! You don't have to live the Christian life alone. You can't live it alone! The Spirit, God's Spirit, is with you at all times!!!
