Trust God's word. The Bible gives you the written promises of God. You can trust the promises of God, because He is the Promise-Keeper. His word of promise is your sure foundation. You can trust God through every situation of life. Trust God with absolute confidence in His word of promise.
All relationships are built upon trust. Your relationship with God is trusting Him. God is trustworthy. As a child will trust his father, so God invites you to trust Him as your Father in heaven. If an earthly father can be trustworthy, your Father in heaven is infinitely much more. In God you trust as your Father in heaven.
Trust God when you don't understand. "Trust in the Lord with all your heart, and lean not on your own understanding"(Proverbs 3:5). We cannot understand all the ways of God. Trusting God is confidently believing in His ability to help us and direct us.
Be willing to trust God in all circumstances. "He is my refuge and my fortress; my God, in Him I will trust" (Psalm 91:2). No one can force you to trust God. On the other hand, no one can stop you from trusting God. If your heart is changed by the grace of God, you will trust in the Lord.
