You did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!” (Romans 8:15). Paul is intent on telling Christians something the Spirit of God does do, and something the Spirit emphatically does not do. Paul insists the Spirit of God does not bring a slavish fear but rather an affectionate crying out to God as our Father.
“Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me“ (Psalm 23:4). We too often talk about God, without talking to God. We can give mental assent to certain Bible teaching – Jesus is Lord, Jesus is a Shepherd, Jesus is awesome – but not say to Jesus, “Rule my life as my Lord, be my Shepherd, help me to walk in awe of you!”
Then David said to the Philistine, “You come to me with a sword and with a spear and with a javelin, but I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have defied” (1 Samuel 17:45). David was victorious over Goliath because he trusted the invisible God with very real and visible and impending problems. But remember this! It is easy to look at someone else’s successful battle, after the fact, and take for granted the outcome.
Do not fear, only believe (Mark 5:36). As you read this, you may at this moment be filled with hope and expectation … or you may be filled with dread and anxiety about the future. Either way, Jesus’ simple words to a suffering man speak volumes. Jesus invites us to rest in him, now and always. But why should we trust Jesus? How can we be certain that he has our best in mind, or that he is working for our good?
