An illustration: When we take that step of faith and we take hold of God’s promises to us in Christ Jesus (have an assistant grab both your arms to illustrate), what happens is that God then takes hold of us and promises that he will never leave us (I also take hold of their arms). Sometimes, however, we allow fear or doubt or wrong behaviour; sin to get the better of us and we let go of God (have the person let go of my arms but keep hold of theirs), but God is not like that: once we have put our trust in him He will never let us go.
