Then I will ask the Father to send you the Holy Spirit who will help you and always be with you. John 14:16
It is hard to face painful situations and not have a support or someone to hold us up so the burden becomes lighter. We, the children of God, must be certain that God is our Helper and that we are not alone, though it may seem so.
Physical presence gives us security because we are used to this, to someone being with us. It is like they share the burden together and they support one another, but the fact of not seeing God physically does not mean that He is not there, for He does not separate from us. And we see Jesus confirmed this when left the Holy Spirit for us, as our Helper.
Let us trust that He is with us to bring the help and the protection we need. Let us not ignore Him; let us allow Him to manifest freely and we will see that He will make himself be felt to give us everything He has and wants for the children of God, even if we cannot see Him.
