Though he falls, he will not be overwhelmed, because the Lord holds his hand.Psalm 37:24(HCSB)
Though we have been eternally saved by grace through faith in Christ, and though we have been eternally freed from slavery to sin and severed from the old sin nature, attacks from without and failures from within can cause every one of us to stumble and fall.
Afflictions, faults, failings, and grievous sins can cause us to stumble and sin, and king David is one such example. But the believer who, like David, is a man after God's own heart, a man who trusts the Word of the Lord, will not be overwhelmed even when he does fall into sin because the Lord has promised to hold his hand.
When we have been eternally saved by grace through faith, our steps are ordered and established by God our Saviour Who is our heavenly intercessor. And though there are times when we will fall into sin, our heavenly Redeemer has promised that we will not be overwhelmed (by the sin we commit - nor the grief that may follow), for He has promised to hold us steady and to order our steps, for our Father takes pleasure in each of His children: "Fear not, for I am with you; Be not dismayed, for I am your God. I will strengthen you, Yes, I will help you, I will uphold you with My righteous right hand."
Let us delight ourselves in the Lord, trust Him implicitly, and commit our ways to Him entirely, for our steps are established by Him and though we may stumble, we will not be overwhelmed for the Lord our God is with us and He has promised to hold our right hand.
Thank You, Lord, that You are holding me steady in Your hand. Keep me from falling, I pray, and establish my goings out and my comings in, from this time forth and even forevermore. In Jesus' name, AMEN.
