I remember when my girls first started to learn to swim. We put floaties on them to make them feel less overwhelmed. To become overwhelmed means to be overcome in mind or feeling.
God knows there are going to be times in our lives where we are going to feel overwhelmed. God gives us a life jacket, Jesus. Jesus when He was overwhelmed separated himself and recharged. “So He Himself often withdrew into the wilderness and prayed.” Luke 5:16 NKJV. Our focus through prayer sets our heart (faith) and our minds (hope) on what God has already done in the here and now; and what we are promised to receive in the future by faith.
